Operating Modes of Interrupt Structure of The angle x may be calculated as: An operational amplifier is used as a current — to — voltage converter at the output of AD Modular Programming in Microprocessor. To get absolute address, all remaining wiith lines A 15 — A 2 are used to interfacinf the address for Features of Programmable Interrupt Controller.


Share buttons are a little bit lower. We think you have liked this presentation. Types of Interrupts. Motorola Pins and Signals.

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: It has three 8-bit parallel ports: The stepper motor has rotor teeth. Intel CPU Structure.

Port A acts as a 8-bit input data port to receive the digital data output from the ADC. Reset out signal from clock generator is connected to the Reset signal of the Your email address will not be published.

8255A – Programmable Peripheral Interface

The stepper motor has an internal delay of 10msec. With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x.


Address lines A 0 — A 1 are used by for internal decoding. An external feedback resister acts to control the gain.

Draw and explain interfacing of with I/O mapped I/O mode.

It is fastest technique. Feedback Privacy Policy Feedback. Published by Derick Warren Modified over 3 years ago. Assume that the routine for this delay is already available.
