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”
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 serial port.
P1.1 — Port 1 bit 1.
RXD — Receiver input for 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
