Address Data bus in 8-bit multiplexed mode
Address bus in 8-bit non-multiplexed mode
Low byte of A D bus in 16-bit multiplexed mode
In Serial Interface mode the following pins have the following meaning
High byte of A D bus in 16-bit multiplexed mode
Data bus in 8-bit non-multiplexed mode
Low speed I O port P1 pins in 8-bit multiplexed mode and serial mode
Port pins have weak pullups until the port is configured by writing to 9FH
and AFH
P2 in all modes
P2 6 is INT
P2 7 is WRH
These pins select one of the four parallel interfaces These pins are
weakly held low during reset
Mode1
ALE used for Intel modes
AS used for non-Intel modes except Mode 3 this pin must be tied high
RD
E used for non-Intel modes except Mode 3 Asynchronous this pin must
be tied high
