Name the modes of 8255 programmable peripheral interface, Computer Engineering

Assignment Help:

What are the different modes in that 8255 Programmable Peripheral Interface (PPI) can operate?

24 I/O lines in 3-8-bit port groups - A, B, C
A, B can be 8-bit input or output ports
C can serve as 2-4-bit input or output ports
3 modes of operation:

- Mode 0: A, B, C simple input or output level sensitive ports

- Mode 1: A, B input or output ports with strobe control in C

- Mode 2: A is bidirectional with control/handshake in B and C
