Port C is further divided into two 4 bit ports i.e. port C lower and port C upper and port C can work in either BSR (bit set rest) mode or in mode 0 of input output mode of 8255. 8255 PPI Chip Block Diagram of the 8255 Chula 2102440 Introduction to Microprocessors 5 I O Mode of the 8255 D7 = 0 > BSR (bit set reset) mode, the bits of port C are programmed individually. 8255 programmable peripheral interface | Architecture | part 1 2 8255 architecture part 1: data bus buffer & read and write control logic. Programmable Peripheral Interface 8255A Peripheral Interface [PPI]. The 8255 has 24 I O pins divided into 3 groups of 8 pins each. The groups are denoted by port A, port B and port C respectively. Every one of the ports can be configured as either an input port or an output port. Block diagram and Pin diagram of 8255: Form the above block diagram it is noticed that any kind of I O devices could be connected with three ports like ... Intel 8255A Programmable Peripheral Interface The 8255A is a general purpose programmable I O device designed to transfer the data from I O to interrupt I O under certain conditions as required. Programmable peripheral interface (8255): Architecture ... Programmable peripheral interface (8255): Architecture, Pin Diagram, Operational Modes and Control Word Format The parallel input output port chip 8255 is also called as programmable peripheral input output port. Intel 8255A Pin Description tutorialspoint This block is responsible for controlling the internal external transfer of data control status word. It accepts the input from the CPU address and control buses, and in turn issues command to both the control groups.
