Function Description The LCD display Module is built in a LSI controller, the controller has two 8-bit registers, an instruction register (IR) and a data register (DR). The IR stores instruction codes, such as display clear and cursor shift, and address information for display data RAM (DDRAM) and character generator (CGRAM). The IR can only be written from the MPU. The DR temporarily stores data to be written or read from DDRAM or CGRAM. When address information is written into the IR, then data is stored into the DR from DDRAM or CGRAM. Address Counter (AC) The address counter (AC) assigns addresses to both DDRAM and CGRAM Display Data RAM (DDRAM) This DDRAM is used to store the display data represented in 8-bit character codes. Its extended capacity is 80×8 bits or 80 characters. Below figure is the relationships between DDRAM addresses and positions on the liquid crystal display. High bits Low bits Example: DDRAM addresses 4E AC (hexadecimal) AC6 AC5 AC4 AC3 AC2 AC1 AC0 1 0 0 1 1 1 0 Display position DDRAM address 1 2 3 4 5 6 00 01 02 03 04 05 40 41 42 43 44 45 7 8 9 10 11 12 13 14 15 16 06 07 08 09 0A 0B 0C 0D 0E 0F 46 47 48 49 4A 4B 4C 4D 4E 4F 2-Line by 16-Character Display Character Generator ROM (CGROM) The CGROM generate 5×8 dot or 5×10 dot character patterns from 8-bit character codes. See Table 2. AMC1602AR-B-B6WTDW-IIC Page 12 Character Generator RAM (CGRAM) In CGRAM, the user can rewrite character by program. For 5×8 dots, eight character patterns can be written, and for 5×10 dots, four character patterns can be written. Write into DDRAM the character code at the addresses shown as the left column of table 1. To show the character patterns stored in CGRAM.
