6.4 6800-Series Parallel Interface (P68=’1’)
The MCU uses a 11-wires 8-data parallel interface or 12-wires 9-data parallel interface or 19-wires 16-data
parallel interface or 21-wires 18-data parallel interface. The chip-select CSX(active low) enables and disables
the parallel interface. RESX(active low) is an external reset signal. WRX is the parallel data write, RDX is the
parallel data read and D[17:0] is parallel data.
The Graphics Controller Chip reads the data at the falling edge of E signal when R/WX=’1’ and writes the data at
the falling of the E signal when R/WX=’0’. The D/CX is the data/command flag. When D/CX=’1’, D[17,0] bits are
display RAM data or command parameters. When D/C=’0’, D[17,0] bits are commands.
The 6800-series bi-direction interface can be used for communication between the micro controller and LCD
driver chip. The selection of this interface is done when P68 pin is high state (VDDI). Interface bus width can be
selected with IM2, IM1 and IM0. The interface function of 6800-series parallel interface are given in Table 6.4.1.
