Table 29. I/O Port Latched Address Output Assignments
Port A and B – Functionality and Structure
Port A and B have similar functionality and structure as shown in Figure 23. The two ports
can be configured to perform one or more of the following functions:
J
MCU I/O Mode
J
GPLD Output – Micro
Cells McellAB[7:4] can be connected to Port A PA[7:4}
or Port B PB[7:4].
J
ECSPLD Output – External chip select output can be connected to either Port A
PA[3:0] or Port PB[3:0].
J
Latched Address output – Provide latched address output per Table 29.
J
Address In – Additional high address inputs using the Input Micro
Cells.
J
Open Drain/Slew Rate – pins PA[3:0] and PB[3:0] can be configured to Open Drain Mode
pins PA[7:4] and PB[7:4] can be configured to fast slew rate
J
Data Port – Port A to D[7:0} for 8 bit non-multiplexed bus
Port B to D[15:8] for 16-bit non-multiplexed bus
J
Peripheral Mode – Port A only
N/A = Not Applicable.
