Port A D Functionality and Structure
Port A is the most flexible of all the I/O ports. It can be configured to perform one or more
of the following functions:
J
Standard MCU I/O Mode
J
PLD I/O
J
Address Out – latched address lines A[0-7] are assigned to pins PA[0-7].
J
Address In – input port for other address lines, inputs can be latched by ALE.
J
Peripheral I/O
Figure 27 shows the structure of a Port A pin. If the pin is configured as an output port,
the multiplexer selects one of its three inputs as output. If the pin is configured as an input,
the input connects to :
1. Data In Register as input in Standard MCU I/O Mode
or
2. PA Macrocell as PLD input
or
3. PA Macrocell through a latch latched by ALE, as Address In input.
Port B D Functionality and Structure
Port B is similar to Port A in structure. It can be configured to perform one or more of the
following functions:
J
Standard MCU I/O Mode
J
PLD I/O
J
Address Out – address lines A[0-7] for 8-bit multiplexed bus or address lines
A[8-15] for 16-bit multiplexed bus are assigned to pins PB[0-7].
Figure 28 shows the structure of a Port B pin. If the pin is configured as an output port,
the multiplexer selects one of its three inputs as output. If the pin is configured as input,
the input connects to :
J
Data In Register as input in Standard MCU I/O Mode
or
J
PB Macrocell as PLD input
