HD61603 Display RAM
The HD61603 has an internal display RAM as shown in Figure 8. Display data is stored in the RAM and
output to the segment output terminal.
Reading Data from Display RAM:
Each bit of the display RAM corresponds to an LCD segment. The
data at segment address SEGn is output to segment output SEGn terminal. Figure 9 shows an example of
the correspondence between the display RAM bit and the display pattern when a 7-segment type LCD is
connected.
Writing Data into Display RAM:
Data is written into the display RAM in the following two methods:
1. Bit manipulation
Data is written into any bit of RAM on a bit basis.
2. Static display mode
8-bit data is written on a digit basis according to the 7-segment type LCD pattern of static drive.
