a) Determine control words when the ports of Intel 8255 are defined as follows: • Port A as an input port. Mode of the Port A is Mode 0. • Port B as an input port. Mode of the Port B is Mode 0. • Port C upper and C lower are input ports. b) Determine the control word for the following configuration of the ports of Intel 8255 for Mode 1 operation: Port A is used as input and operation mode of Port A is Mode 1. • Port B can be used as output and operates in Mode 1. • PC6 and PC7 act as input.
