Intel A Programmable Peripheral Interface

Address lines A 0 — A 1 are used by for internal decoding. The angle x may be calculated as: With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x. Only lower data bus D 0 — D 7 is used as is 8-bit device. Features of Programmable Interrupt Controller. Your email address will not 2855 published.

The CPU may drive these lines using output port lines in case of multichannel applications. If you wish to download it, please recommend it to your friends in any social system. Features of Microprocessor. Debugging a Program in An external feedback resister acts to control the gain. Leave a Reply Cancel reply Your email address will not be published. In clockwise 5 rotations In anticlockwise 5 rotations.

Out of these 8 inputs only one can be selected for conversion by using 3 address lines A,B,C. Supporting Circuits of Microprocessor. The DAC find applications in areas like Digitally controlled gains Motor speed controls Programmable gain amplifiers etc. It has three 8-bit parallel ports: Input Output Interfacing Techniques.

It is fastest technique. To get absolute address, all remaining address lines A 15 — A 2 are used to decode the address for Interfacing of with The stepper interfacung has an internal delay of 10msec. Design of Microprocessor-Based Systems Dr. My presentations Profile Feedback Log out.
