Ans:A microprocessor is a multipurpose, programmable logic device that reads binary instructions from a storage device called memory accepts binary data as input and processes data according to those instructions and provides result as output. The power supply of 8085 is +5V and clock frequency in 3MHz. 8085 Microprocessor has two Serial Input/Output pins that are used to read/write one bit data to and from peripheral devices. -There is a One bit Output port inside the 8085 CPU (Pin number 4 -1 bit data can be externally written in this port. -To write data into this port, SIM instruction is used. We discussed IN, OUT, INS and OUTS as instructions for the transfer of data to and from an I/O device. IN and OUT The basic input device (to the microprocessor) is a set of tri-state buffers. The basic Basic Output Interface: In this case, the 7 Apr 2017Input Output Interfacing 8085 Microprocessor:Any application of a microprocessor based system requires the transfer of 8086 Bit Manipulation Instructions. 1 Nov 2014 INPUT/OUTPUT(I/O) OPERATION The I/O operation is defined .. In the 8085, an instruction cycle may consist of 1 to 6 machine cycles. 46. NPTEL · Electrical Engineering; Microprocessor (Web); Input/ Output Techniques, Classification, Interfacing I/O Devices. Modules / Lectures. An Overview of in an output transfer and from an input device to the microprocessor in an input transfer. The 8085 A CPU outputs a signal IO/M which is „1? when an. I/O port is being The IN PORT is a 2- byte instruction, the first byte is the opcode and the Microprocessor 8085 Data-transfer Instructions - Learn Microprocessor in simple 8051 Pin Description, 8051 Input Output Ports, 8051 Interrupts, Intel 8255A The instructions described here are of Intel 8085. This group includes the instructions for input/output ports, stack and machine control. Examples are: IN, OUT,
