These are 8-bit bi-directional buses, connected to data bus for transferring data. When it is low, then data is transfer from Port A is working as 8-bit bidirectional.
Any port can be used as an input or output port. Outputs are latchedInputs are buffered not latched. IO Interfaces and Bus Standards.
This is a 8-bit Unlatched buffer Input and an Output latch.
It can be programmed by mode 0 and mode 1. This is Active Low signal, when it is Low Write operation will be start. Address signals are Fevice CS. About project SlidePlayer Terms of Service. It is a programmable device. Used to interface between data bus with system bus.

The 8 bit data port can be either used as input or output port. In this modetwo 8 bit ports port A and port B and two 4 mkltipurpose ports port C upper and port C lower are available.
These lines are divided into two groups. This is Active Low signal. This programnable used to reset the device. It is a 8-bit bidirectional Data bus.
