Description :

One intermediate shale used for parallel interfacing is the Programmable Peripheral Interface (PPI) 8255. This flake is manufactured by Intel Corporation and packaged in the form of a 40 pin dual in line package and designed for a variety of interface functions in the microprocessor. PPI 8255 has 24 I / O pins which are divided into three 8-bit ports. These ports are port A (PA0-PA7), port B (PB0-PB7) and port C (PC0-PC7). As a path for transferring data to and from PPI 8255 an 8 bit data bus channel (D0-D7) is provided. The data bus from this PPI can be connected directly to the data bus from a microcomputer.
