Ports A and B – Functionality and Structure

Ports A and B have similar functionality and struc-

ture, as shown in Figure 61. 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 91., page 115.

■ 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)
