Enable Out
The Enable Out register can be read by the micro-
controller. It contains the output enable values for
a given port. A
1
indicates the driver is in output
mode. A
0
indicates the driver is in tri-state and
the pin is in input mode.
Ports A and B
Functionality and Structure
Ports A and B have similar functionality and struc-
ture, as shown in Figure
29
. 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 21., page 55
.
Address In
Additional high address inputs
using the Input Macrocells (IMC).
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.
Data Port
Port A to D7-D0 for 8 bit non-
multiplexed bus
Multiplexed Address/Data port for certain
types of MCU bus interfaces.
Peripheral Mode
