I/O
Port 3: Port 3 is an 2-bit I/O port with a user-congurable output type. During reset
Port 3 latches are congured 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 conguration
selected. Each port pin is congured independently. Refer to Section 8.12.1 “Port
All pins have Schmitt triggered inputs.
Port 3 also provides various special functions as described below:
7
I/O
P3.0 — Port 3 bit 0.
O
XTAL2 — Output from the oscillator amplier (when a crystal oscillator option is
selected via the FLASH conguration.
O
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 real time clock/system timer.
6
I/O
P3.1 — Port 3 bit 1.
I
XTAL1 — Input to the oscillator circuit and internal clock generator circuits (when
selected via the FLASH conguration). 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 real time clock/system timer.
