Web1 Answer. 8255 is a programmable peripheral interface. It is used to interface microprocessor with I/O devices via three ports: PA, PB and PC. All ports are 8-bit and bidirectional. 8255 transfers data with the microprocessor through its 8-bit data bus. The two address lines A1 and A0 are used to make internal selection in 8255. WebModes of Operation of 8255 Microprocessor: Bit Set-Reset (BSR) Mode: The individual bits of Port C can be set or reset by sending out a single OUT instruction to the control register. When Port C is used for control/status operation, this feature can be used to set or reset individual bits. I/O Modes: Mode 0 : Simple input/output:
