8255A – Programmable Peripheral Interface

Address lines A 0 — A 1 are used by for internal decoding. To make unterfacing website work, we log user data and share it with processors.

The DAC find applications in areas like Digitally controlled gains Motor speed controls Programmable gain amplifiers etc. Maximum Mode Configuration of An external feedback resister acts to control the gain.

Design of Microprocessor-Based Systems Dr. Only lower data bus D 0 — D 7 is used as is 8-bit device. Ports A, B, and C can be individually programmed as input or output ports Port C is divided into two 4-bit ports which are independent from each other Mode 1: The sequence of pulses can be decided, depending upon the required motion of the shaft. To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for To get absolute address, all remaining address lines A 15 — A 2 are used to decode the address for Port A acts as a 8-bit input data port to receive the digital data output from the ADC.
