These lines are divided into two groups. Improved dc driving capability.
This is Active Low signal, when it is Low Write operation will be start. This is used to select the ports. Used to interface between data bus with system bus. Any port can be used as an input or output port.
8155 Programmable Interface
Both the inputs and outputs are latched. It is splitted into two parts. On one side we have data bus. About project Multiputpose Terms of Service.
To make this website work, we log user data and share it with processors. That means clear control registers. This is Active Low signal, when it is Low read operation will be start. A BSR word is written for each bit Example: When it multiipurpose low, then data is transfer from These are 8-bit bi-directional buses, connected to data multipurposr for transferring data.
Ports do not have Handshake or interrupt capability. It can be programmed by mode 0 and mode 1. The internal data bus and Outer pins D0-D7 pins are connected in internally.
It is a programmable device. The 8 bit data port can be either used as input or output port. Address signals are A0,A1,and CS. Published by Jaidyn Tea Modified over 3 years ago.
multipurpoes It can be programmed by mode 0mode 1, mode 2. If you wish to download it, please recommend it to your friends in any social system.

8155 It is a 8-bit bidirectional Data bus. We think you have liked this presentation. This mode allows bidirectional data transfer over a single 8-bit data bus port A using handshake signals.
