Ports A and B – Functionality and Structure
Ports A and B have similar functionality and struc-
ture, as shown in Figure
65
. The two ports can be
configured to perform one or more of the following
functions:
MCU I/O Mode
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.
CPLD Input – Via the Input Macrocells (IMC).
Latched Address output – Provide latched
address output as per
Table 94., page 121
.
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.
Peripheral Mode – Port A only (80-pin
package)
