8085 INTERFACING WITH 8255 PDF
Problem – Interface with microprocessor and write an assembly Subtract content of two ports by interfacing with microprocessor. The interfacing happens with the ports of the Microprocessor. The main IC’s which are to be interfaced with are: 1. PPI. 2. PIC. 3. USART. PPI: 82C55 The 82C55 is a popular interfacing component, that can interface any TTL-compatible I/O device to the microprocessor.

To get absolute address, all remaining address lines A 15 — A 2 are used to decode the address for By using indirect address method this range can be extended upto 2 16 addresses. Only lower data bus D 0 — D 7 is used as is 8-bit device. Reset out signal from clock generator is connected to the Reset signal of the Address lines A 0 — A 1 are used by for internal decoding.
To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for In this section iterfacing discuss many useful applications like keyboard and display interface, traffic light control, printer interface and so on. Your email address will not be published.
