9 COM/60 SEG LCD Driver

Column Address Counter

The column address counter is an 8-bit preset counter which provides a DDRAM

column address, and is independent of page address register.

It will increment (+1) the column address whenever “display data read” or “display

data write” instructions are issued. However, the incrementing of column address is

stopped at column address 65H. The count-lock will be released by the “column

address set” instruction again. The counter can inverts the correspondence between

the column address and segment driver direction by means of “ADC select”

instruction.

Page Address Register

The page address register provides a DDRAM page address. The Page Address 6 is

used for icon display, and only D0 is valid.

Figure 9 LCD Driver Circuits

This driver circuit is configured by 8-common drivers, 60-segment drivers and 1-icon-

common driver. This LCD panel driver voltage depends on the combination of

display data and FR (internal) signal.

7.3.1 Display Data Latch Circuit

The display data latch circuit is a latch that temporarily stores the display data that is

output to the liquid crystal driver circuit from the display data RAM. “Display on/off”,

“Inverse display on/off” and “Entire display on/off” instructions control only the

contents of this latch circuit, they cannot change the contents of the DDRAM.
