Interfacing of 8085 with 8255 Programmable Peripheral Interface
The Intel 8255 (or i8255) Programmable Peripheral Interface (PPI) chip was developed and manufactured by Intel in the first half of the 1970s for the Intel 8080 microprocessor. The 8255 provides 24 parallel input/output lines with a variety of programmable operating modes. The 8255 is a member of the … See more The 8255 has a similar function to the Motorola 6820 PIA (Peripheral Interface Adapter) from the Motorola 6800 family, also originally packaged as 40-pin DIL. The 8255 provides 24 I/O pins with four programmable … See more The 8255 gives a CPU or digital system access to programmable parallel I/O. The 8255 has 24 input/output pins. These are divided into three 8 … See more The Bit Set/Reset (BSR) mode is available on port C only. Each line of port C (PC7 - PC0) can be set or reset by writing a suitable value to the control word register. BSR mode and I/O mode are independent and selection of BSR mode does not affect the operation of … See more • drew.hickmans.net, Complete Description about the Intel 8255 IC • ic-on-line.cn, Datasheet • sharpmz.org, functions overview See more The 8255 was widely used in many microcomputer/microcontroller systems and home computers such as the SV-328 and all See more There are two basic operational modes of 8255: • Bit Set/Reset mode (BSR mode). • Input/Output mode (I/O mode). The two modes are selected on the basis of the value present … See more This mode is selected when D7 bit of the Control Word Register is 1. There are three I/O modes: 1.
