9.4.5 Ports A and B – Functionality and Structure
Ports A and B have similar functionality and structure, as shown in Figure 20. The two
ports can be configured to perform one or more of the following functions:
J
MCU I/O Mode
J
GPLD Output – Combinatorial PLD outputs can be connected to Port A or Port B.
J
PLD Input
– Input to the PLDs.
J
Latched Address output – Provide latched address output per Table 30.
J
Address In – Additional high address inputs, may be latched by ALE.
J
Open Drain/Slew Rate – pins PA[3:0] and PB[3:0] can be configured to fast slew rate,
pins PA[7:4] and PB[7:4] can be configured to Open Drain
Mode.
J
Data Port – Port A only, connect to non-multiplexed 8-bit data bus.

9.4.4 Port Data Registers
The Port Data Registers, shown in Table 28, are used by the microcontroller to write data
to or read data from the ports. Table 28 shows the register name, the ports having each
register type, and microcontroller access for each register type. The registers are
described below.
9.4.4.1 Data In
Port pins are connected directly to the Data In buffer. In MCU I/O input mode, the pin input
is read through the Data In buffer.
9.4.4.2 Data Out Register
Stores output data written by the MCU in the MCU I/O output mode. The contents of the
Register are driven out to the pins if the Direction Register or the output enable
product term is set to “1”. The contents of the register can also be read back by the
microcontroller.
