INTERFACE WITH MPU
1) Interface with 8-bit MPU
When interfacing data length are 8-bit, transfer is performed all at once through 8 ports, from DB0 to DB7.
Example of timing sequence is shown below.

2) Interface with 4-bit MPU
When interfacing data length is 4-bit, only 4 ports, from DB4 to DB7, are used as data bus. 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 parts. Busy Flag outputs "1"
after the second transfer are ended. Example of timing sequence is shown below.
