25
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.

I/O
P2.6 — Port 2 bit 6.
P2.7

I/O
P2.7 — Port 2 bit 7.
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”
and Table 11 “Static characteristics” for details.
All pins have Schmitt triggered inputs.
Port 3 also provides various special functions as described
below:
P3.0/XTAL2/
CLKOUT
7
12
6
I/O
P3.0 — Port 3 bit 0.
O
XTAL2 — Output from the oscillator amplier (when a crystal
oscillator option is selected via the ash 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
6
11
5
I/O
P3.1 — Port 3 bit 1.
I
XTAL1 — Input to the oscillator circuit and internal clock
generator circuits (when selected via the ash 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.
P4.0 to P4.7
I/O
Port 4: Port 4 is an 8-bit I/O port with a user-congurable
output type. During reset Port 4 latches are congured in the
input only mode with the internal pull-up disabled. The
operation of Port 4 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”
