Preset count is loaded – OUT is high. To make this website work, we log user data and share it with processors. Pin Diagram of Debugging a Program in Ports are configured as input ports Input on reset CS – Used to select the chip. To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for GATE can be connected to line and made 1 by software.
Mode 5 – Hardware Triggered strobe. Published by Derick Warren Modified over 3 years ago. Explain the mode of operation and initialisation. The sequence of pulses can be decided, depending upon the required motion of the shaft.

Thus a clock pulse of desired frequently can be produced. Once solution is similar to – This can be solved in many ways.
Modular Programming in Microprocessor. Mode Interrupt on terminal count.
No continuous pulses are generated. Types of Interrupts. Explain the mode of operation and initialization.
Supporting Circuits of Microprocessor. When Read back command for status is sent to control register. To rotate the shaft of the stepper motor, a sequence of pulses is intwrfacing to be applied to the windings of the stepper intrefacing, in a proper sequence.
To make this website work, we log user data and share it with processors. To get absolute address, all remaining address lines A 15 — A 2 are used to decode the address for Maximum Mode Configuration of The DAC find applications in areas like Digitally controlled gains Motor speed controls Programmable gain amplifiers etc.
My presentations Profile Feedback Log out. Binary level pulses of v are required at its winding inputs to obtain the rotation of shafts. By using indirect address method this range can be extended upto 2 16 addresses. About project SlidePlayer Terms of Service.
