MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -SID – SID denotes serial input data pin and its pin is numbered as 5. With this pin, data is serially fed to the processor directly through the input devices. SOD – SOD denotes serial output data pin and its pin number is 4, in the pin configuration of 8085.

Detailed explanation-2: -This is offered with CLK pin. Its frequency is continually similar because the frequency at which the microprocessor works. This is a serial i/p data, and the information on this pin is uploaded into the 7th-bit of the accumulator while RIM (Read Interrupt Mask) instruction is performed.

Detailed explanation-3: -8085 Microprocessor has two Serial Input/Output pins that are used to read/write one bit data to and from peripheral devices.

Detailed explanation-4: -Ans: SID (Serial input data line): It is an input line through which the microprocessor accepts serial data. SOD (Serial output data line): It is an output line through which the microprocessor sends output serial data.
