Reading Data from HD61604 Display RAM:
A display RAM segment address corresponds to a
segment output. The data at segment address SEGn is output to segment output SEGn pin.
A common address corresponds to the output timing of a common output and a segment output. The same
common address data is simultaneously read. The data of display RAM is reproduced on the LCD panel.
The following shows the correspondence between the 7-segment type LCD connection and the display
RAM in each mode.
1. Static drive
In the static drive, only the column of COM0 of display RAM is output. COM1 to COM3 are not
displayed (Figure 4).
2. 1/2 duty cycle drive
In the 1/2 duty cycle drive, the columns of COM0 and COM1
of display RAM are output in time
sharing. The columns of COM2 and COM3 are not displayed (Figure 5).
