Ports A and B – Functionality and Structure
Ports A and B have similar functionality and struc-
ture, as shown in Figure 25. The two ports can be
configured to perform one or more of the following
functions:
s
MCU I/O Mode
s
CPLD Output – Macrocells McellAB7-McellAB0
can be connected to Port A or Port B. McellBC7-
McellBC0 can be connected to Port B or Port C.
s
CPLD Input – Via the Input Macrocells (IMC).
s
Latched Address output – Provide latched
address output as per Table 21.
s
Address In – Additional high address inputs
using the Input Macrocells (IMC).
s
Open Drain/Slew Rate – pins PA3-PA0 and
PB3-PB0 can be configured to fast slew rate,
pins PA7-PA4 and PB7-PB4 can be configured
to Open Drain Mode.
s
Data Port – Port A to D7-D0 for 8 bit non-
multiplexed bus
s
Multiplexed Address/Data port for certain types
of MCU bus interfaces.
s
Peripheral Mode – Port A only
