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
I
Two Groups (Group A and Group B) .
I
Each Group contains one 8-bit data port and one 4-bit
control/data port,
I
The 8-bit data port can be either input or output, Both
inputs and outputs are latched,
I
The 4-bit port is used for control and status of the 8-bit data
port.
