5.1.2 80-series MPU Interface
The MCU uses an 11-wires 8-data or 19-wires 16-data or 27-wires 24-data parallel interface.
The chip-select CSX (active low) enables and disables the parallel interface. WRX is the parallel data write, RDX
is the parallel data read and D[23:0] is parallel data.
The Graphics Controller Chip reads the data at the rising edge of WRX signal. The D/CX is the data/command
flag. When D/CX=’1’, D[23:0] bits are display RAM data or command parameters. When D/C=’0’, D[23:0] bits are
commands.
The 8080-series bi-directional interface can be used for communication between the micro controller and LCD
driver chip. Interface bus width can be selected with IM3,IM2, IM1 and IM0.
The interface functions of 80-series parallel interface are given in Table 5.1.2.
