In
Port 2 is an 8-bit, bidirectional, CMOS-compatible I/O port (see
lines can be independently configured under software control as inputs or outputs. Port 2
is always available for I/O operation. A mask option is available to connect eight pull-up
transistors on this port. Bits programmed as output are globally programmed as either
push-pull or open-drain. The POR resets with the eight bits of Port 2 configured as inputs.
Port 2 also has an 8-bit input OR and AND gate, which can be used to wake up the part.
P20 can be programmed to access the edge-detection circuitry in DEMODULATION
mode.
