RAM data or address bus
For 4-bit bus mode, RAMD [3:0] is valid and RAMD [7:4] is not
used, it must be connected to VDD or VSS level.
For 8-bit bus mode, RAMD [7:0] is valid.
LCD load signal between one common signal to another.
MAIN=1: master outputs a LOAD signal
MAIN=0: slave accepst the signal from the master
Liquid crystal alternating current signal I/O terminal.
MAIN=1: master unit outputs an FR signal
MAIN=0: slave accepts the signal from the master
