7-3 DISPLAY DATA RAM (DDRAM)
7.3.1 DDRAM
It is 396 X 132 X 4 bits capacity RAM prepared for storing dot data. You can access a desired bit by specifying the page
address and column address. Since display data from MCU D7 to D0 and D15 to D8 correspond to one or two pixels of
RGB, data transfer related restrictions are reduced, realizing the display flexing.
The RAM on ST7632 is separated to a block per 4 lines to allow the display system to process data on the block basis.
MPU
’s read and write operations to and from the RAM are performed via the I/O buffer circuit; Reading of the RAM for the
liquid crystal drive is controlled from another separate circuit. Refer to the following memory map for the RAM
configuration.
