RW1067 can transfer data in bus mode (4-bit or 8-bit) or serial mode with MPU. User can use any type
4 or 8- bit MPU.
In case of 4-bit bus mode, data transfer is performed by two times to transfer 1 byte data.
At first higher 4-bit (in case of 8-bit bus mode, the contents of DB4 - DB7) are transferred, and then
lower 4- bit (in case of 8-bit bus mode, the contents of DB0 - DB3) are transferred. So transfer is
performed by two times. Busy Flag outputs "High" after the second transfer are ended.
DB7.
When interfacing data length is 4-bit, only 4 ports, from DB4 - DB7, are used as data bus.
When interfacing data length are 8-bit, transfer is performed at a time through 8 ports, from DB0 -
If PSB is set to "High”, Parallel bus mode is set 4-bit or 8-bit.
