INTERFACE WITH MPU
INTERFACE WITH 8-BIT MPU
With 8-bit interfacing data length transfer is performed at a time through 8 ports, from DB0 - DB7. Example of timing
sequence is shown below.

INTERFACE WITH 4-BIT MPU
When interfacing data length are 4-bit, only 4 ports, from DB4 - 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, then the lower 4-bit (in case of 8-bit bus mode, the
contents of DB0-DB3) are transferred. So transfer is performed twice. Busy Flag outputs "High" after the second
transfer are ended. Example of timing sequence is shown below.
