KS0074 34COM/80SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
Interface with MPU in Bus Mode
1) Interface with 8-bits MPU
If 8-bits MPU is used, KS0074 can connect directly with that.
In this case, port E, RS, R/W and DB0 to DB7 need to interface each other.
Example of timing sequence is shown below.
Fig 11. Example of 8-bit Bus Mode Timing Sequence
2) Interface with 4-bits MPU
If 4-bits MPU is used, KS0074 can connect directly with this.
In this case, port E, RS, R/W and DB4 to DB7 need to interface each other. The transfer is performed by twice.
Example of timing sequence is shown below.
