OPERATING MODE 1

(Strobed Input/Output)

This functional configuration provides a means for

transferring l/O data to or from a specified port in conjunction

with strobes or handshaking signals. In mode 1, port A and

port B use the lines on port C to generate or accept these

handshaking signals

s Two Groups (Group A and Group B) .

s Each Group contains one 8-bit data port and one 4-bit

control/data port,

s The 8-bit data port can be either input or output, Both

inputs and outputs are latched,

s The 4-bit port is used for control and status of the 8-bit data

port.
