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 8.12.1 “Port conﬁgurations” and Table 8 “DC

electrical characteristics” for details.

All pins have Schmitt triggered inputs.

Port 2 also provides various special functions as described below:

I/O

P2.0 — Port 2 bit 0.

ICB — Input Capture B.

I/O

P2.1 — Port 2 bit 1.

OCD — Output Compare D.

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.

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.

I/O

P2.4 — Port 2 bit 4.

SS — SPI Slave select.

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.

I/O

P2.6 — Port 2 bit 6.

OCA — Output Compare A.

I/O

P2.7 — Port 2 bit 7.

ICA — Input Capture A.
