P2.4 —
Port 2 bit 4.
SS —
SPI Slave select.
P2.5 —
Port 2 bit 5.
SPICLK —
SPI clock. When configured as master, this pin is output;
when configured as slave, this pin is input.
P2.6 —
Port 2 bit 6.
OCA —
Output Compare A.
P2.7 —
Port 2 bit 7.
ICA —
Input Capture A.
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
Section 7.13.1 “Port configurations”
and
Table 10 “DC electrical characteristics”
for details.
All pins have Schmitt triggered 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.
