INTERFACE WITH MPU
KS0078 can transfer data in bus mode (4-bit or 8-bit) or serial mode with MPU. Hence, both types of 4 or 8-bit MPU can be used.
In case of 4-bit bus mode, data transfer is performed by twice to transfer 1 byte data.
(1) When interfacing data length are 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 twice. Busy Flag outputs "High" after
the second transfer is ended.
(2) When interfacing data length are 8-bit, transfer is performed at a time through 8 ports, from DB0 to DB7.
(3) If IM is set to "Low", serial transfer mode is set.
