Description
Port 3: Port 3 is a 2-bit I/O port with a user-configurable output type.
During reset Port 3 latches are configured in the input only mode with the
internal pull-up disabled. The operation of Port 3 pins as inputs and
outputs depends upon the port configuration selected. Each port pin is
configured independently. Refer to
and
All pins have Schmitt trigger inputs.
Port 3 also provides various special functions as described below:
P3.0 — Port 3 bit 0.
XTAL2 — Output from the oscillator amplifier (when a crystal oscillator
option is selected via the flash configuration.
CLKOUT — CPU clock divided by 2 when enabled via SFR bit (ENCLK -
TRIM.6). It can be used if the CPU clock is the internal RC oscillator,
watchdog oscillator or external clock input, except when XTAL1/XTAL2 are
used to generate clock source for the RTC/system timer.
P3.1 — Port 3 bit 1.
XTAL1 — Input to the oscillator circuit and internal clock generator circuits
(when selected via the flash configuration). It can be a port pin if internal
RC oscillator or watchdog oscillator is used as the CPU clock source, and
if XTAL1/XTAL2 are not used to generate the clock for the RTC/system
timer.
Ground: 0 V reference.
Power supply: This is the power supply voltage for normal operation as
well as Idle and Power-down modes.
