P2.0 to P2.7

I/O Port 2: Port 2 is an 8-bit I/O port with a user-configurable output type.

During reset Port 2 latches are configured in the input only mode with the

internal pull-up disabled. The operation of Port 2 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 9 “Static characteristics” for details.

All pins have Schmitt trigger inputs.

Port 2 also provides various special functions as described below:

P2.0/ICB

1

25

I/O P2.0 — Port 2 bit 0.

I

ICB — Input Capture B.

P2.1/OCD

2

26

I/O P2.1 — Port 2 bit 1.

O OCD — Output Compare D.

P2.2/MOSI 13

9

I/O P2.2 — Port 2 bit 2.

I/O MOSI — SPI master out slave in. When configured as master, this pin is

output; when configured as slave, this pin is input.

P2.3/MISO 14

10

I/O P2.3 — Port 2 bit 3.

I/O MISO — When configured as master, this pin is input, when configured as

slave, this pin is output.

P2.4/SS

15

11

I/O P2.4 — Port 2 bit 4.

I

SS — SPI Slave select.

P2.5/SPICLK 16

12

I/O P2.5 — Port 2 bit 5.

I/O SPICLK — SPI clock. When configured as master, this pin is output; when

configured as slave, this pin is input.

P2.6/OCA

27

23

I/O P2.6 — Port 2 bit 6.

O OCA — Output Compare A.

P2.7/ICA

28

24

I/O P2.7 — Port 2 bit 7.

I

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-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 9 “Static characteristics” for details.

All pins have Schmitt trigger inputs.

Port 3 also provides various special functions as described below:

P3.0/XTAL2/ 9

5

I/O P3.0 — Port 3 bit 0.

CLKOUT

O XTAL2 — Output from the oscillator amplifier (when a crystal oscillator

option is selected via the flash configuration.

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.
