16COM / 40SEG 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 at a time through 8 ports, from DB0 to DB7.
Example of timing sequence is shown below.
Figure 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, the higher 4-bit (in case of 8-bit bus mode, the contents of DB4 - DB7), and 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 is ended.
Example of timing sequence is shown below.
