16COM / 80SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
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.
An Example of the timing sequence is shown below.
Fig-4. Example of 8-bit Bus Mode Timing Diagram
2) Interface with 4-bit MPU
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 the lower 4-bit
(in case of 8-bit bus mode, the contents of DB0 - DB3) are transferred. So transfer is performed in two parts. Busy
Flag outputs “1” after the second transfer are ended.
Example of timing sequence is shown below.
