If 8-bits MPU is used, RW1068 can connect directly with that. In this case, port E, RS, R/W and DB0
to DB7 need to interface each other. Example of timing sequence is shown below.
If 4-bit MPU is used, RW1068 can connect directly with this. In this case, port E, RS, R/W and DB4 -
DB7 need to interface each other. The transfer is performed by two times. Example of timing
sequence is shown below.
