9.4.5 Ports A, B and C – Functionality and Structure
Ports A and B have similar functionality and structure, as shown in Figure 21. The two
ports can be configured to perform one or more of the following functions:
t MCU I/O Mode
t GPLD Output – Combinatorial PLD outputs.
t PLD Input
– Input to the PLDs.
t Address In – Additional high address inputs may be latched by ALE.
t Open Drain/Slew Rate – pins PC[7:0]can be configured to fast slew rate,
pins PA[7:0] and PB[7:0] can be configured to Open Drain
Mode.
