LCD RAM.
The data to be displayed by the LCD is written to a 90 byte display RAM located at
locations $0930 thru $095C and $0A30 thru $0A5C in the memory map. The bits
are organized according to Table 12-1 and Table 12-2, with a 1 stored in a given
location resulting in the corresponding display segment being activated. The LCD
RAM is a dual port RAM that interfaces with the internal address and data buses
of the MCU. It is possible to read from LCD RAM locations for scrolling purposes.
When the display is disabled, the LCD RAM can be used as on-chip RAM.
