I/O
P2.4 — Port 2 bit 4.
I
SS — SPI Slave select.
P2.5/SPICLK

I/O
P2.5 — Port 2 bit 5.
I/O
SPICLK — SPI clock. When congured as master, this pin is output;
when congured as slave, this pin is input.
P2.6/OCA

ICA — Input Capture A.
P3.0 to P3.1
I/O
Port 3: Port 3 is a 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 7.13.1 “Port congurations”
All pins have Schmitt triggered inputs.
Port 3 also provides various special functions as described below:
P3.0/XTAL2/
CLKOUT
9
5
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 RTC/system timer.
P3.1/XTAL1
8
4
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
RTC/system timer.

Power Supply: This is the power supply voltage for normal operation as
well as Idle and Power-down modes.
