IO Interfaces and Bus Standards. It can be programmed by mode 0 and mode 1. This is used to select the ports.

T Pprogrammable L compatible. Port A is working as 8-bit bidirectional. Improved dc driving capability. The internal data bus and Outer pins D0-D7 pins are connected in internally. To make this website work, we log user data and share it with processors. When it is low, then data is transfer from About project SlidePlayer Terms of Service.

In this modetwo 8 bit ports port A and port B and two 4 bit ports port C upper and port C lower are available. This is Active Low signal. The 8 bit data port can be either used multipkrpose input or output port. It is splitted into two parts.

These are 8-bit bi-directional buses, connected to data bus for transferring data. Both the inputs and outputs are latched. This is Active Low signal, when it is Low read operation will be start. This is Active Low signal, when it is Low Write operation will be start.


Address signals are A0,A1,and CS. That means clear control registers. Ports do not have Handshake or interrupt capability. It is a 8-bit bidirectional Data bus.


This mode allows bidirectional data transfer over a single 8-bit data multiurpose port A using handshake signals. If you wish to download it, please recommend it to your friends in any social system. It is a programmable device. Share buttons are a little bit lower.
