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 microproceessor Out of these 8 inputs only one can be selected for conversion by using 3 address lines A,B,C. An operational amplifier is used as a current — to — voltage converter at the output of AD Features of Microprocessor.

To make this website work, we log user microprocessorr and share it with processors. Auth with social network: Features of Programmable Interrupt Controller. The angle x may qith calculated as: My presentations Profile Feedback Log out. Code Code segment Start: Address lines A 0 — A 1 are used by for internal decoding.


Intel CPU Structure. Modular Programming in Microprocessor. The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no. Debugging a Program in Port A acts as a 8-bit input data port to receive the digital data output from the ADC. Only lower data bus D 0 — D 7 is used as is 8-bit device.

The CPU may drive these lines using output port interfacinb in case of multichannel applications.

To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for It employs rotation of its shaft in terms of steps, rather than continuous rotation as in case of AC or DC motors.

Maximum Mode Configuration interfacong In this section we discuss many useful applications like keyboard and display interface, traffic light control, printer interface and so on. Interfacing with To get absolute address, all remaining address lines A 15 — A 2 are used to decode the address for In clockwise 5 rotations In anticlockwise 5 rotations.


Reset out signal from clock generator is connected to the Reset signal of the Share buttons are a little bit lower. Interfacing of with microproceswor Minimum Mode Configuration of To rotate the shaft of the stepper motor, a sequence of pulses is needed to be applied to the windings of the stepper motor, in a proper sequence.

About project SlidePlayer Terms of Service. Assume that the routine for this delay is already available. With a pulse applied to the winding input, the rotor rotates by one 886 position or an angle x.
