DATA PORT
ADDRESS OFFSET = 00H
The Data Port is located at an offset of ‘00H’ from the base address. The data register is cleared at
initialization by RESET. During a WRITE operation, the Data Register latches the contents of the internal
data bus. The contents of this register are buffered (non inverting) and output onto the PD0 - PD7 ports.
During a READ operation in SPP mode, PD0 - PD7 ports are buffered (not latched) and output to the host
CPU.
