Description
Port 2: Port 2 is a 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 the
section on I/O port configuration and the DC Electrical Characteristics for details.
This port is not available in 20-pin package and is configured automatically as
outputs to conserve power. The alternate functions for these pins must not be
enabled.
All pins have Schmitt triggered inputs.
Port 2 also provides various special functions as described below.
P2.0 — Port 2 bit 0.
P2.1 — Port 2 bit 1.
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 — SPI master in slave out. 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.
P2.7 — Port 2 bit 7.
