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 7.16.1 “Port configurations”
details.
All pins have Schmitt trigger inputs.
Port 2 also provides various special functions as described below:
P2.0 — Port 2 bit 0.
ICB — Input Capture B.
DAC0 — Digital-to-analog converter output.
AD03 — ADC0 channel 3 analog input.
P2.1 — Port 2 bit 1.
OCD — Output Compare D.
AD02 — ADC0 channel 2 analog input.
P2.2 — Port 2 bit 2.
MOSI — SPI master out slave in. When configured as master, this pin is output;
when configured as slave, this pin is input.
P2.3 — Port 2 bit 3.
MISO — When configured as master, this pin is input, when configured as slave,
this pin is output.
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 7.16.1 “Port configurations”
details.
All pins have Schmitt trigger inputs.
Port 3 also provides various special functions as described below:
