Pin Functions 5.2.1. Power supply Pin Name VDD VSS Function 2.7 to 5.5V supply. This may be the same supply as the controlling microprocessor. Ground Note: The peak supply current drawn by the S1D13305 series may be up to ten times the average supply current. The power supply impedance must be kept as low as possible by ensuring that supply lines are sufficiently wide and by placing 0.47 µF decoupling capacitors that have good high-frequency response near the device’s supply pins. 5.2.2. Oscillator Pin Name XG XD Function Crystal connection for internal oscillator (See section 13). This pin can be driven by an external clock source that satisfies the timing specifications of the EXT φ0 signal (See section 6.3.6). Crystal connection for internal oscillator.

The S1D13305 series output buffers are enabled when this signal is active. When the 6800 family interface is selected, this signal acts as the active-HIGH enable clock. Data is read from or written to the S1D13305 series when this clock goes HIGH. When the 8080 family interface is selected, this signal acts as the active-LOW write strobe. The bus data is latched on the rising edge of this signal. WR or R/W When the 6800 family interface is selected, this signal acts as the read/write control signal. Data is read from the S1D13305 series if this signal is HIGH, and written to the S1D13305 series if it is LOW. Chip select. This active-LOW input enables the S1D13305 series. It is usually connected to the output of an address decoder device that maps the S1D13305 series into the memory space of the controlling microprocessor. This active-LOW input performs a hardware reset on the S1D13305 series. It is a Schmitt-trigger input for enhanced noise immunity; however, care should be taken to ensure that it is not triggered if the supply voltage is lowered. CS RES 5.2.4.

LCD drive signals In order to provide effective low-power drive for LCD matrixes, the S1D13305 series can directly control both the X- and Y-drivers using an enable chain. Pin Name XD0 to XD3 XSCL XECL LP Function 4-bit X-driver (column drive) data outputs. Connect these outputs to the inputs of the X-driver chips. The falling edge of XSCL latches the data on XD0 to XD3 into the input shift registers of the X-drivers. To conserve power, this clock halts between LP and the start of the following display line (See section 6.3.7). The falling edge of XECL triggers the enable chain cascade for the X-drivers. Every 16th clock pulse is output to the next X-driver. LP latches the signal in the X-driver shift registers into the output data latches. LP is a fallingedge triggered signal, and pulses once every display line. Connect LP to the Y-driver shift clock on modules. LCD panel AC drive output. The WF period is selected to be one of two values with SYSTEM SET command. The falling edge of YSCL latches the data on YD into the input shift registers of the Y-drivers. YSCL is not used with driver ICs which use LP as the Y-driver shift clock. YD is the data pulse output for the Y drivers. It is active during the last line of each frame, and is shifted through the Y drivers one by one (by YSCL), to scan the display’s common connections. Power-down output signal. YDIS is HIGH while the display drive outputs are active. YDIS goes LOW one or two frames after the sleep command is written to the S1D13305 series. All Y-driver outputs are forced to an intermediate level (de-selecting the display segments) to blank the display. In order to implement power-down operation in the LCD unit, the LCD power drive supplies must also be disabled when the display is disabled by YDIS. WF YSCL YD YDIS 6. SPECIFICATIONS 6.1.

In general, the internal registers of the S1D13305 series are modified as each command parameter is input. However, the microprocessor does not have to set all the parameters of a command and may send a new command before all parameters have been input. The internal registers for the parameters that have been input will have been changed but the remaining parameter registers are unchanged. 2-byte parameters (where two bytes are treated as 1 data item) are handled as follows: a. CSRW, CSRR: Each byte is processed individually. The microprocessor may read or write just the low byte of the cursor address. b. SYSTEM SET, SCROLL, CGRAM ADR: Both parameter bytes are processed together. If the command is changed after half of the parameter has been input, the single byte is ignored. 2. APL and APH are 2-byte parameters, but are treated as two 1-byte parameters. 20 EPSON S1D13305 Series Technical Manual INSTRUCTION SET 8.2. System Control Commands 8.2.1.

Cancels sleep mode Parameters following P1 are not needed if only canceling sleep mode. 8.2.1.2. M0 Selects the internal or external character generator ROM. The internal character generator ROM contains 160, 5 × 7 pixel characters, as shown in figure 70. These characters are fixed at fabrication by the metallization mask. The external character generator ROM, on the other hand, can contain up to 256 user-defined characters. M0 = 0: Internal CG ROM M0 = 1: External CG ROM Note that if the CG ROM address space overlaps the display memory address space, that portion of the display memory cannot be written to. 8.2.1.3. M1 Selects the memory configuration for user-definable characters. The CG RAM codes select one of the 64 codes shown in figure 46. M1 = 0: No D6 correction. The CG RAM1 and CG RAM2 address spaces are not contiguous, the CG RAM1 address space is treated as character generator RAM, and the CG RAM2 address space is treated as character generator ROM. M1 = 1: D6 correction. The CG RAM1 and CG RAM2 address spaces are contiguout and are both treated as character generator RAM. S1D13305 Series Technical Manual EPSON 21 INSTRUCTION SET 8.2.1.4. M2 Selects the height of the character bitmaps. Characters more than 16 pixels high can be displayed by creating a bitmap for each portion of each character and using the S1D13305 series graphics mode to reposition them. M2 = 0: 8-pixel character height (2716 or equivalent ROM) M2 = 1: 16-pixel character height (2732 or equivalent ROM) 8.2.1.5. W/S Selects the LCD drive method.

IV Screen origin compensation for inverse display. IV is usually set to 1. The best way of displaying inverted characters is to Exclusive-OR the text layer with the graphics background layer. However, inverted characters at the top or left of the screen are difficult to read as the character origin is at the top-left of its bitmap and there are no background pixels either above or to the left of these characters. S1D13305 Series Technical Manual EPSON 23 INSTRUCTION SET The IV flag causes the S1D13305 series to offset the text screen against the graphics back layer by one vertical pixel. Use the horizontal pixel scroll function (HDOT SCR) to shift the text screen 1 to 7 pixels to the right. All characters will then have the necessary surrounding background pixels that ensure easy reading of the inverted characters. See Section 10.5 for information on scrolling. IV = 0: Screen top-line correction IV = 1: No screen top-line correction Display start point Back layer HDOT SCR Character IV 1 dot 8.2.1.7. FX Define the horizontal character size. The character width in pixels is equal to FX + 1, where FX can range from 00 to 07H inclusive. If data bit 3 is set (FX is in the range 08 to 0FH) and an 8-pixel font is used, a space is inserted between characters. Table 3.

IV and HDOT SCR adjustment Since the S1D13305 series handles display data in 8-bit units, characters larger than 8 pixels wide must be formed from 8-pixel segments. As Figure 6 shows, the remainder of the second eight bits are not displayed. This also applies to the second screen layer. In graphics mode, the normal character field is also eight pixels. If a wider character field is used, any remainder in the second eight bits is not displayed. FX FX FY 8 bits FY 8 bits 8 bits 8 bits Address A Address B Non-display area Figure 6.

WF = 0: 16-line AC drive WF = 1: two-frame AC drive In two-frame AC drive, the WF period is twice the frame period. In 16-line AC drive, WF inverts every 16 lines. Although 16-line AC drive gives a more readable display, horizontal lines may appear when using high LCD drive voltages or at high viewing angles. 8.2.1.9. FY Sets the vertical character size. The height in pixels is equal to FY + 1. FY can range from 00 to 0FH inclusive. Set FY to zero (vertical size equals one) when in graphics mode. Table 4.

C/R Sets the address range covered by one display line, that is, the number of characters less one, multiplied by the number of horizontal bytes per character. C/R can range from 0 to 239. For example, if the character width is 10 pixels, then the address range is equal to twice the number of characters, less 2. See Section 16.1.1 for the calculation of C/R. [C/R] cannot be set to a value greater than the address range. It can, however, be set smaller than the address range, in which case the excess display area is blank.

This command has no parameter bytes. At least one blank frame after receiving this command, the S1D13305F halts all internal operations, including the oscillator, and enters the sleep state. 1. The YDIS signal goes LOW between one and two frames after the SLEEP IN command is received. Since YDIS forces all display driver outputs to go to the deselected output voltage, YDIS can be used as a power-down signal for the LCD unit. This can be done by having YDIS turn off the relatively highpower LCD drive supplies at the same time as it blanks the display. 2. Since all internal clocks in the S1D13305 series are halted while in the sleep state, a DC voltage will be applied to the LCD panel if the LCD drive supplies remain on. If reliability is a prime consideration, turn off the LCD drive supplies before issuing the SLEEP IN command. 3. Note that, although the bus lines become high impedance in the sleep state, pull-up or pull-down resistors on the bus will force these lines to a known state.

Virtual and physical screen relationship 9.2.2. Display address scanning The S1D13305 series scans the display memory in the same way as a raster scan CRT screen. Each row is scanned from left to right until the address range equals C/R. Rows are scanned from top to bottom. In graphics mode, at the start of each line, the address counter is set to the address at the start of the previous line plus the address pitch, AP. In text mode, the address counter is set to the same start address, and the same character data is read, for each row in the character bitmap. However, a new row of the character generator output is used each time. Once all the rows in the character bitmap have been displayed, the address counter is set to the start address plus AP and the next line of text is displayed. 42 EPSON S1D13305 Series Technical Manual DISPLAY CONTROL FUNCTIONS 1 • • • 8 9 • • • 16 17 • • • 24 • • • • SAD SAD + 1 SAD + 2 SAD + C/R SAD + AP SAD + AP +1 SAD + AP +2 SAD + AP + C/R SAD + 2AP C/R W/S = 0, FX = 8, FY = 8 Figure 29.

Cursor register function The S1D13305 series cursor address register functions as both the displayed cursor position address register and the display memory access address register. When accessing display memory outside the actual screen memory, the address register must be saved before accessing the memory and restored after memory access is complete. Cursor display address register Cursor register Address pointer Although the cursor is normally displayed for character data, the S1D13305 series may also display a dummy cursor for graphical characters. This is only possible if the graphics screen is displayed, the text screen is turned off and the microprocessor generates the cursor control address. D=1 FC1 = 0 Cursor ON FC0 = 1 Figure 34. Cursor addressing Note that the cursor may disappear from the display if the cursor address remains outside the displayed screen memory for more than a few hundred milliseconds. FP1 = 0 FP0 = 0 Block screen 1 (character screen) OFF 9.3.2. Cursor movement On each memory access, the cursor address register changes by the amount previously specified with CSRDIR, automatically moving the cursor to the desired location. FP3 = 0 FP2 = 1 Block screen 2 (graphics screen) ON 9.3.3. Cursor display layers Although the S1D13305 series can display up to three layers, the cursor is displayed in only one of these layers: Two-layer configuration: First layer (L1) Three-layer configuration: Third layer (L3) The cursor will not be displayed if it is moved outside the memory for its layer. Layers may be swapped or the cursor layer moved within the display memory if it is necessary to display the cursor on a layer other than the present cursor layer. Figure 35. Cursor display layers Consider the example of displaying Chinese characters on a graphics screen. To write the display data, the cursor address is set to the second screen block, but the cursor is not displayed. To display the cursor, the cursor address is set to an address within the blank text screen block. Since the automatic cursor increment is in address units, not character units, the controlling microprocessor must set the cursor address register when moving the cursor over the graphical characters. 46 EPSON S1D13305 Series Technical Manual DISPLAY CONTROL FUNCTIONS 8 dots 8 dots 8 dots 8 dots Block cursor 18 dots Auto shift Auto shift Auto shift Cursor address preset Figure 36. Cursor movement If no text screen is displayed, only a bar cursor can be displayed at the cursor address. If the first layer is a mixed text and graphics screen and the cursor shape is set to a block cursor, the S1D13305 series automatically decides which cursor shape to display. On the text screen it displays a block cursor, and on the graphics screen, a bar cursor. S1D13305 Series Technical Manual EPSON 47 DISPLAY CONTROL FUNCTIONS 9.4. Memory to Display Relationship The S1D13305 series supports virtual screens that are larger than the physical size of the LCD panel address range, C/R. A layer of the S1D13305 series can be considered as a window in the larger virtual screen held in display memory. This window can be divided into two blocks, with each block able to display a different portion of the virtual screen. This enables, for example, one block to dynamically scroll through a data area while the other acts as a status message display area. See Figure 37 and 38.

Scrolling The controlling microprocessor can set the S1D13305 series scrolling modes by overwriting the scroll address registers SAD1 to SAD4, and by directly setting the scrolling mode and scrolling rate. Since the S1D13305 series does not automatically erase the bottom line, it must be erased with blanking data when changing the scroll address register. 9.5.1.

Internal character generator The internal character generator is recommended for minimum system configurations containing a S1D13305 series, display RAM, LCD panel, single-chip microprocessor and power supply. Since the internal character generator uses a CMOS mask ROM, it is also recommended for low-power applications. • 5 × 7-pixel font (See Section 17.) • 160 JIS standard characters • Can be mixed with character generator RAM (maximum of 64 CG RAM characters) • Can be automatically spaced out up to 8 × 16 pixels 10.1.3. Character generator RAM The user can freely use the character generator RAM for storing graphics characters. The character generator RAM can be mapped by the microprocessor anywhere in display memory, allowing effective use of unused address space. • Up to 8 × 8-pixel characters (M2 = 0) or 8 × 16 characters (M2 = 1) • Up to 256 characters if mapped at F000H to FFFFH (64 if used together with character generator ROM) • Can be mapped anywhere in display memory address space if used with the character generator ROM • Mapped into the display memory address space at F000H to F7FFH if not used with the character generator ROM (more than 64 characters are in the CG RAM). Set SAG0 to F000H and M1 to zero when defining characters number 193 upwards. 10.1.2. External character generator ROM The external CG ROM can be used when fonts other than those in the internal ROM are needed. Data is stored in the external ROM in the same format used in the internal ROM. (See Section 10.3.) • Up to 8 × 8-pixel characters (M2 = 0) or 8 × 16-pixel characters (M2 = 1) • Up to 256 characters (192 if used together with the internal ROM) • Mapped into the display memory address space at F000H to F7FFH (M2 = 0) or F000H to FFFFH (M2 = 1) • Characters can be up to 8 × 16-pixels; however, excess bits must be set to zero. 54 EPSON S1D13305 Series Technical Manual CHARACTER GENERATOR 10.2. CG Memory Allocation Since the S1D13305 series uses 8-bit character codes, it can handle no more than 256 characters at a time.

M1 = 1 The S1D13305 series automatically converts all bits set in bit 6 of character code for CG RAM 2 to zero. Because of this, the CG RAM data areas become contiguous in display memory. When writing data to CG RAM: • Calculate the address as for M1 = 0. • Change bit 6 of the character code from “1” to “0”. 56 EPSON S1D13305 Series Technical Manual CHARACTER GENERATOR 10.3.2. CG RAM addressing example • Define a pattern for the “A” in Figure 26. • The CG RAM table start address is 4800H. • The character code for the defined pattern is 80H (the first character code in the CG RAM area). As the character code table in Figure 46 shows, codes 80H to 9FH and E0H to FFH are allocated to the CG RAM Table 23. Character data example and can be used as desired. 80H is thus the first code for CG RAM. As characters cannot be used if only using graphics mode, there is no need to set the CG RAM data.

MICROPROCESSOR INTERFACE 11.1. System Bus Interface SEL1, SEL2, A0, RD, WR and CS are used as control signals for the microprocessor data bus. A0 is normally connected to the lowest bit of the system address bus. SEL1 and SEL2 change the operation of the RD and WR pins to enable interfacing to either an 8080 or 6800 family bus, and should have a pull-up or pull-down resistor. With microprocessors using an 8080 family interface, the S1D13305 series is normally mapped into the I/O address space. Display flicker may occur if there is more than one consecutive access that cannot be ignored within a frame. The microprocessor can minimize this either by performing these accesses intermittently, or by continuously checking the status flag (D6) and waiting for it to become HIGH. 11.2.1. Display status indication output When CS, A0 and RD are LOW, D6 functions as the display status indication output. It is HIGH during the TV-mode vertical retrace period or the LCD-mode horizontal retrace period, and LOW, during the period the controller is writing to the display. By monitoring D6 and writing to the data memory only during retrace periods, the display can be updated without causing screen flicker. 11.1.1. 8080 series Table 24. 8080 series interface signals A0 RD WR Function 0 0 1 Status flag read Display data and cursor address 1 0 1 read 0 1 0 Display data and parameter write 1 1 0 Command write 11.2.2. Internal register access The SYSTEM SET and SLEEP IN commands can be used to perform input/output to the S1D13305 series independently of the system clock frequency. These are the only commands that can be used while the S1D13305 series is in sleep mode. 11.1.2. 6800 series Table 25. 6800 series interface signals A0 R/W E Function 0 1 1 Status flag read Display data and cursor address 1 1 1 read 0 0 1 Display data and parameter write 1 0 1 Command write 11.2.3. Display memory access The S1D13305 series supports a form of pipelined processing, in which the microprocessor synchronizes its processing to the S1D13305 series timing. When writing, the microprocessor first issues the MWRITE command. It then repeatedly writes display data to the S1D13305 series using the system bus timing. This ensures that the microprocessor is not slowed down even if the display memory access times are slower than the system bus access times. See Figure 47. When reading, the microprocessor first issues the MREAD command, which causes the S1D13305 series to load the first read data into its output buffer. The microprocessor then reads data from the S1D13305 series using the system bus timing. With each read, the S1D13305 series reads the next data item from the display memory ready for the next read access. See Figure 48. 11.2. Microprocessor Synchronization The S1D13305 series interface operates at full bus speed, completing the execution of each command within the cycle time, tCYC . The controlling microprocessor’s performance is thus not hampered by polling or handshaking when accessing the S1D13305 series.

Display memory read cycle Note A possible problem with the display memory read cycle is that the system bus access time, tACC, does not depend on the display memory access time, tACV. The microprocessor may only make repeated reads if the read loop time exceeds the S1D13305 series cycle time, tCYC. If it does not, NOP instructions may be inserted in the program loop. tACC, tACV and tCYC limits are given in section 6.2. 60 EPSON S1D13305 Series Technical Manual MICROPROCESSOR INTERFACE 11.3.

Supply Current during Display Memory Access The 24 address and data lines of the S1D13305 series cycle at one-third of the oscillator frequency, fOSC. The charge and discharge current on these pins, IVOP, is given by the equation below. When IVOP exceeds IOPR, it can be estimated by: IVOP ∝ C V f where C is the capacitance of the display memory bus, V is the operating voltage, and f is the operating frequency. If VOPR = 5.0V, f = 1.0 MHz, and the display memory bus capacitance is 1.0 pF per line: IVOP ≤ 120 µA / MHz × pF To reduce current flow during display memory accesses, it is important to use low-power memory, and to minimize both the number of devices and the parasitic capacitance. 13. OSCILLATOR CIRCUIT The S1D13305 series incorporates an oscillator circuit. A stable oscillator can be constructed simply by connecting an AT-cut crystal and two capacitors to XG and XD, as shown in the figure below. If the oscillator frequency is increased, CD and CG should be decreased proportionally. Note that the circuit board lines to XG and XD must be as short as possible to prevent wiring capacitance from changing the oscillator frequency or increasing the power consumption. S1D13305 series XG CG XD CD = 3 to 20 pF CD CG = 2 to 18 pF Load impedance = 700 Ω (max) Figure 52. Crystal oscillator 14. STATUS FLAG The S1D13305 series has a single bit status flag. D6: X line standby D7 X D6 X X X X X D0 X X: Don’t care The D6 status flag is HIGH for the TC/R-C/R cycles at the end of each line where the S1D13305 series is not reading the display memory. The microprocessor may use this period to update display memory without affecting the display, however it is recommended that the display be turned off when refreshing the whole display. Figure 53.

Yes Data Input No Data Input ? Yes Figure 55. Flowchart for busy flag checking • Precaution on the write timing to VRAM The allowable writing duration is since “5 × 9 × tOSC” has elapsed (tOSC = 1/fOSC: a cycle of the oscillation frequency) from the positive going edge of LP up to {(TCR) – (C/R) – 7} × 9 × tOSC. Currently employed D6 status flag reading method does not identify the timing when the read D6 = Low took place. Thus, negative going edge of LP should be used as the interrupt signal when implementing the writing in above timing. If you try to access the display memory in other timing than the above, flickering of the display screen will result. 64 EPSON S1D13305 Series Technical Manual RESET/APPLICATION NOTES 15. RESET VDD 1ms reset pulse RES 0.7 VDD 0.3 VDD Figure 56. Reset timing The S1D13305 series requires a reset pulse at least 1 ms long after power-on in order to re-initialize its internal state. For maximum reliability, it is not recommended to apply a DC voltage to the LCD panel while the S1D13305 series is reset. Turn off the LCD power supplies for at least one frame period after the start of the reset pulse. The S1D13305 series cannot receive commands while it is reset. Commands to initialize the internal registers should be issued soon after a reset. During reset, the LCD drive signals XD, LP and FR are halted. A delay of 3 ms (maximum) is required following the rising edges of both RES and VDD to allow for system stabilization. 16. APPLICATION NOTES 16.1. Initialization Parameters The parameters for the initialization commands must be determined first. Square brackets around a parameter name indicate the number represented by the parameter, rather than the value written to the parameter register. For example, [FX] = FX + 1. Ì TC/R TC/R must satisfy the condition [TC/R] ≥ [C/R] + 4. Ì fOSC and fFR Once TC/R has been set, the frame frequency, fFR, and lines per frame [L/F] will also have been set. The lower limit on the oscillator frequency fOSC is given by: fOSC ≥ ([TC/R] × 9 + 1) × [L/F] × fFR Ì If no standard crystal close to the calculated value of fOSC exists, a higher frequency crystal can be used and the value of TC/R revised using the above equation. Ì Symptoms of an incorrect TC/R setting are listed below. If any of these appears, check the value of TC/ R and modify it if necessary. • Vertical scanning halts and a high-contrast horizontal line appears. • All pixels are on or off. • The LP output signal is absent or corrupted. • The display is unstable. 16.1.1. SYSTEM SET instruction and parameters Ì FX The horizontal character field size is determined from the horizontal display size in pixels [VD] and the number of characters per line [VC]. [VD] / [VC] ≤ [FX] Ì C/R C/R can be determined from VC and FX. [C/R] = RND ([FX] / 8) × [VC] where RND(x) denotes × rounded up to the next highest integer.

System Overview Figure 61 shows the S1D13305 series in a typical system. The microprocessor issues instructions to the S1D13305 series, and the S1D13305 series drives the LCD panel and may have up to 64KB of display memory. Since all of the S1D13305 series Character generator External character generator memory LCD control circuits are integrated onto the S1D13305 series, few external components are required to construct a complete medium- resolution liquid crystal display.

Smooth Horizontal Scrolling Figure 63 illustrates smooth display scrolling to the left. When scrolling left, the screen is effectively moving to the right, over the larger virtual screen. Instead of changing the display start address SAD and shifting the display by eight pixels, smooth scrolling is achieved by repeatedly changing the pixel-shift parameter of the HDOT SCR command. When the display has been scrolled seven pixels, the HDOT SCR pixel-shift parameter is reset to zero and SAD incremented by one. Repeating this operation at a suitable rate gives the appearance of smooth scrolling. HDOT SCR parameter SAD To scroll the display to the right, the reverse procedure is followed. When the edge of the virtual screen is reached, the microprocessor must take appropriate steps so that the display is not corrupted. The scroll must be stopped or the display modified. Note that the HDOT SCR command cannot be used to scroll individual layers.

HDOT SCR example Note: The response time of LCD panels changes considerably at low temperatures. Smooth scrolling under these conditions may make the display difficult to read.

It allows the display of inverse characters, half-intensity menu pads and flashing of selected screen areas. These functions are controlled by the OVLAY and DISP ON/ OFF commands.

Layer synthesis A number of means can be used to achieve these effects, depending on the display configuration. These are listed below. Note, however, that not all of these can be used in the one layer at the same time. 16.5.2. Half-tone display The FP parameter can be used to generate half-intensity display by flashing the display at 17 Hz. Note that this mode of operation may cause flicker problems with certain LCD panels. 16.5.2.1. Menu pad display Turn flashing off for the first layer, on at 17 Hz for the second layer, and combine the screens using the OR function. 1. OVLAY: P1 = 00H 2. DISP ON/OFF: P1 = 34H 16.5.1.

Graph display To present two overlaid graphs on the screen, configure the display as for the menu bar display and put one graph on each screen layer. The difference in contrast between the half- and full-intensity displays will make it easy to distinguish between the two graphs and help create an attractive display. 1. OVLAY: P1 = 00H 2. DISP ON/OFF: P1 = 34H 16.5.3. Flashing areas 16.5.3.1 Small area To flash selected characters, the MPU can alternately write the characters as character codes and blank characters at intervals of 0.5 to 1.0 seconds. 16.5.3.2. Large area Divide both layer 1 and layer 2 into two screen blocks each, layer 2 being divided into the area to be flashed and the remainder of the screen. Flash the layer 2 screen block at 2 Hz for the area to be flashed and combine the layers using the OR function. ABC ABC XYZ XYZ Figure 66. Localized flashing 16.6. 16 × 16-dot Graphic Display 16.6.1. Command usage This example shows how to display 16 × 16-pixel characters. The command sequence is as follows: CSRW Set the cursor address. CSRDIR Set the cursor auto-increment direction. MWRITE Write to the display memory. 16.6.2. Kanji character display The program for writing large characters operates as follows: 1. The microprocessor reads the character data from its ROM. 2. The microprocessor sets the display address and writes to the VRAM. The flowchart is shown in Figure 69.
