I Register select
Used as register selection input.
When RS = “High”, Data register is
selected.
When RS = “Low”, Instruction register is
selected.
MPU
I Read/Write
Used as read/write selection input.
When RW = “High”, read operation.
When RW = “Low”, write operation.
MPU
I Read/Write enable Used as read/write enable signal.
MPU
I/O Data bus 0-7
In 8-bit bus mode, used as low order
bidirectional data bus.
In 4-bit bus mode, open these pins.
MPU
In 8-bit bus mode, used as high order
bidirectional data bus.
In 4-bit bus mode, used as both high and
low order.
DB7 used for Busy Flag output.
