5.3 Reset Function
An internal reset circuit automatically initializes the module when the power is turn on.
The following instructions are executed during the initialization.
5.3.1 Power-on reset
allowing interfacing with 4-bit or 8-bit MPUs.
For 8-bit interface data, all eight bus lines (DB0 to DB7) are used.
1) Display clear
2) Set the address counter to 00H
For 4-bit interface data, only four bus lines (DB4 to DB7) are used for transfer. When to use 4-bit
The busy flag (BF) are performed before transferring the higher 4 bits. BF checks are not required
parallel data transfer, DB0 to DB3 keep “H”or “L”. The data transfer between the VFD module and
the MPU is completed after the 4-bit data has been transferred before the four low order bits (for 8-bit
operation. DB0 to DB3).
