8155/6 Multifunction Device (memory+IO)

Auth with social network: This is used to select multupurpose ports. Ports do not have Handshake or interrupt capability. Share buttons are a little bit lower. A BSR word is written for each bit Example: On one side we have data bus. It can be programmed by mode 0mode 1, mode 2. Improved dc driving capability.


It can be programmed by mode 0 and mode 1. These are 8-bit bi-directional buses, connected to data bus for transferring data. This is Active Low signal, when it is Low Write operation will be start.


To make this website work, we log user data and share it with processors. This is Active Low signal, when it is Low read operation will be start. When it is low, then data is transfer from Published by Jaidyn Tea Modified over 3 years ago.

My presentations Profile Feedback Log out. This is Active Low signal. This mode allows bidirectional data transfer over a single 8-bit data bus port A using handshake signals. IO Interfaces and Bus Standards. If you wish to download it, please recommend it to your friends in any social system. The internal data bus and Outer pins D0-D7 pins are connected in internally.

Used to interface between data bus with system bus. Port A is working as 8-bit bidirectional.

The 8 bit data port can be either used as input or output port. It is a programmable device. We think you have liked this presentation. Any port can be used as an input or output port.


These lines are divided into two groups. It is a 8-bit bidirectional Data bus. That means clear control registers.

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. To use this website, you must agree to pfogrammable Privacy Policyincluding cookie policy. This is used to reset the device. Registration Forgot your password?

Programable is splitted into two parts. T T L compatible. This is a 8-bit Unlatched buffer Input and an Output latch. Outputs are latchedInputs are buffered not latched.
