Port 1: Port 1 is an 8-bit I/O port with a user-configurable output type,
except for three pins as noted below. During reset Port 1 latches are
configured in the input only mode with the internal pull-up disabled. The
operation of the configurable Port 1 pins as inputs and outputs depends
upon the port configuration selected. Each of the configurable port pins
are programmed independently. Refer to
configurations”
P1.3 are open drain when used as outputs. P1.5 is input only.
All pins have Schmitt trigger inputs.
Port 1 also provides various special functions as described below:
P1.0 — Port 1 bit 0.
TXD — Transmitter output for the serial port.
P1.1 — Port 1 bit 1.
RXD — Receiver input for the serial port.
P1.2 — Port 1 bit 2 (open-drain when used as output).
T0 — Timer/counter 0 external count input or overflow output (open-drain
when used as output).
SCL — I
P1.3 — Port 1 bit 3 (open-drain when used as output).
INT0 — External interrupt 0 input.
SDA — I
P1.4 — Port 1 bit 4.
INT1 — External interrupt 1 input.
