PD5 is I/O and TCAP/PD7 is input-only shared with the timer input capture. The address of the port D data register is $0003 and the data direction register is at address $0007. Reset does not affect the data registers, but clears the data direction registers, thereby returning the ports to inputs. Writing a one to a DDR bit sets the corresponding port bit to output mode. The TCAP/PD7 pin controls the input capture feature for the on-chip programmable timer. This pin can be read at any time even if the TCAP function is enabled. CH IVE DB YF RE The address of the port C data register is $0002 and the data direction register is at address $0006. Reset does not affect the data registers, but clears the data direction registers, thereby returning the ports to inputs. Writing a one to a DDR bit sets the corresponding port bit to output mode. Two of the port C pins, PC0 and PC1, have a higher current drive capability. See SECTION 13 ELECTRICAL SPECIFICATIONS. ES CA GENERAL DESCRIPTION 1-6 For More Information On This Product, Go to: www.freescale.com LE When the A/D converter is enabled, PC7 becomes VRH, and PC6–PC3 become AN0–AN3 (analog inputs 0–3). The values of CH1 and CH0 in the A/D status and control register (ADSCR) select one of the four pins as the input to the A/D converter. When the A/D converter is enabled a digital read of port C gives a logical zero from the selected analog input pin. A digital read of port C’s remaining pins gives their correct digital values. VRH is the positive (high) reference voltage for the A/D converter. VSS is the negative (low) reference voltage. A reset turns off the A/D converter and configures port C as a general-purpose I/O port. See SECTION 10 ANALOG-TO-DIGITAL (A/D) CONVERTER. SE MIC ON DU Port C, as an 8-bit shared function port, shares five of its pins with the A/D converter. When the A/D converter is not enabled, PC7–PC0 form an 8-bit general-purpose bidirectional I/O port. The contents of data direction register C (DDRC) determine whether each pin is an input or an output. CT OR , IN C.2 006 Port B is a 3-bit bidirectional port. These pins are shared with the SIOP subsystem. Refer to SECTION 7 SIMPLE SERIAL INPUT/OUTPUT PORT for a detailed description of the SIOP. The address of the port B data register is $0001 and the data direction register is at address $0005. Reset does not affect the data registers, but clears the data direction registers, thereby returning the ports to inputs. Writing a one to a DDR bit sets the corresponding port bit to output mode.

GENERAL RELEASE SPECIFICATION The counter alternate register differs from the counter register in one respect: Aread of the counter register MSB can clear the timer overflow flag (TOF). Therefore, the counter alternate register can be read at any time without the possibility of missing timer overflow interrupts due to clearing of the TOF. The free-running counter is configured to $FFFC during reset and is always a read-only register. During a power-on reset, the counter is also preset to $FFFC and begins running after the oscillator start-up delay. Because the free-running counter is 16 bits preceded by a fixed divided-by-four prescaler, the value in the free-running counter repeats every 262,144 internal bus clock cycles. When the counter rolls over from $FFFF to $0000, the TOF bit is set. An interrupt can also be enabled when counter rollover occurs by setting its interrupt enable bit (TOIE). Freescale Semiconductor, Inc... The processor can write to either byte of the output compare register without affecting the other byte. The output level (OLVL) bit is clocked to the output level register regardless of whether the output compare flag (OCF) is set or clear. TIMER Rev. 2.0 For More Information On This Product, Go to: www.freescale.com 8-3 AR CH After a processor write cycle to the output compare register containing the MSB ($16), the output compare function is inhibited until the LSB ($17) is also written. The user must write both bytes (locations) if the MSB is written first. A write made only to the LSB ($17) will not inhibit the compare function. The free-running counter is updated every four internal bus clock cycles. The minimum time required to update the output compare register is a function of the program rather than the internal hardware. IVE DB YF The output compare register contents are compared with the contents of the freerunning counter continually, and if a match is found, the corresponding output compare flag (OCF) bit is set and the corresponding output level (OLVL) bit is clocked to an output level register. The output compare register values and the output level bit should be changed after each successful comparison to establish a new elapsed timeout. An interrupt can also accompany a successful output compare provided the corresponding interrupt enable bit (OCIE) is set. RE ES CA The 16-bit output compare register is made up of two 8-bit registers at locations $16 (MSB) and $17 (LSB). The output compare register is used for several purposes, such as indicating when a period of time has elapsed. All bits are readable and writable and are not altered by the timer hardware or reset. If the compare function is not needed, the two bytes of the output compare register can be used as storage locations. LE SE MIC 8.2 Output Compare Register ON DU CT OR , IN C.2 006 times. This buffer is accessed when reading the free-running counter or counter alternate register LSB ($19 or $1B) and, thus, completes a read sequence of the total counter value.

GENERAL RELEASE SPECIFICATION 8.3 Input Capture Register The result obtained by an input capture will be one more than the value of the free-running counter on the rising edge of the internal bus clock preceding the external transition.

SE MIC After a read of the input capture register ($14) MSB, the counter transfer is inhibited until the LSB ($15) is also read. This characteristic causes the time used in the input capture software routine and its interaction with the main program to determine the minimum pulse period. ON The free-running counter contents are transferred to the input capture register on each proper signal transition regardless of whether the input capture flag (ICF) is set or clear. The input capture register always contains the free-running counter value that corresponds to the most recent input capture.

If an IRQ is used to exit stop mode, the COP counter will not be reset after the 4064-cycle delay and will have that many cycles already counted when control is returned to the program. YF RE ES CA The COP will continue to operate normally during wait or halt mode. The software should pull the device out of wait or halt mode periodically and reset the COP by writing a logic zero to the COPR bit to prevent a COP reset.

Each channel of conversion takes 32 internal clock cycles, and the clock frequency must be equal to or greater than 1 MHz. If the internal clock frequency is less than 1 MHz, the A/D internal RC oscillator (nominally 1.5 MHz) must be used for the A/D conversion clock. Make this selection by setting the ADRC bit in the A/D status and control register to logical one. ANALOG-TO-DIGITAL (A/D) CONVERTER 10-1 RE ES CA An analog input voltage equal to VRH converts to digital $FF; an input voltage greater than VRH converts to $FF with no overflow. An analog input voltage equal to VSS converts to digital $00. For ratiometric conversions, the source of each analog input should use VRH as the supply voltage and be referenced to VSS. LE SE A multiplexer selects one of four analog input channels (AN3, AN2, AN1, or AN0) for sampling. A comparator successively compares the output of an internal digital-to-analog (D/A) converter to the sampled analog input. Control logic changes the D/A converter input one bit at a time, starting with the most significant bit (MSB), until the D/A converter output matches the sampled analog input.

Motorola keeps this code confidential and uses it only to expedite ROM pattern generation in case of any difficulty with the object code. Label the diskette with the file name of the source code. 15.3 ROM Program Verification Freescale Semiconductor, Inc... AR After receiving the signed listing verify form, Motorola manufactures a custom photographic mask. The mask contains the customer’s application program and is used to process silicon wafers. The application program cannot be changed after the manufacture of the mask begins. Motorola then produces 10 MCUs, called RVUs, and sends the RVUs to the customer. RVUs are usually packaged in unmarked ceramic and tested to 5 Vdc at room temperature. RVUs are not tested to environmental extremes because their sole purpose is to demonstrate that the customer’s user ROM pattern was properly implemented. The 10 RVUs are free of charge with the minimum order quantity. These units are not to be used for qualification or production. RVUs are not guaranteed by Motorola Quality Assurance. CH IVE DB YF 15.4 ROM Verification Units (RVUs) Rev. 2.0 For More Information On This Product, Go to: www.freescale.com RE ES Check the listing verify file thoroughly, then complete and sign the listing verify form and return the listing verify form to Motorola. The signed listing verify form constitutes the contractual agreement for the creation of the custom mask. CA To aid the customer in checking the listing verify file, Motorola will program the listing verify file into customer-supplied blank preformatted Macintosh or DOS disks. All original pattern media are filed for contractual purposes and are not returned. ORDERING INFORMATION 15-3 LE SE MIC Motorola inputs the customer’s application program code into a computer program that generates a listing verify file. The listing verify file represents the memory map of the MCU. The listing verify file contains the user ROM code and may also contain non-user ROM code, such as self-check code. Motorola sends the customer a computer printout of the listing verify file along with a listing verify form. ON DU The primary use for the on-chip ROM is to hold the customer’s application program. The customer develops and debugs the application program and then submits the MCU order along with the application program. CT OR , IN C.2 006 If the memory map has two user ROM areas with the same address, then write the two areas in separate files on the diskette. Label the diskette with both file names. Freescale Semiconductor, Inc. GENERAL RELEASE SPECIFICATION Freescale Semiconductor, Inc...
