7. Controller data

7.1 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. By the

register selector (RS) signal, these two registers can be selected.

RS R/W Operation

0 0 IR write as an internal operation (display clear, etc.)

0 1 Read busy flag (DB7) and address counter (DB0 to DB7)

1 0 Write data to DDRAM or CGRAM (DR to DDRAM or CGRAM)

1 1 Read data from DDRAM or CGRAM (DDRAM or CGRAM to DR)

Busy Flag (BF)

When the busy flag is 1, the controller LSI is in the internal operation mode and the next instruction will

not be accepted. When RS=0 and R/W=1, the busy flag is output to DB7. The next instruction mustbe written after ensuring that the busy flag is 0.

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 808 bits or 80 characters. Below figure is the relationship between DDRAM addresses and

positions on the liquid crystal display.

Example: 2-Line by 16-Character Display

Character Generator ROM (CGROM)

The CGROM generate 58 dot or 510 dot character patterns from 8-bit character codes. See Table 2.

7.2 Character Generator RAM (CGRAM)

In CGRAM, the user can rewrite character by program. For 58 dots, eight character patterns can be

written, and for 510 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.
