Description
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:
P2.0 — Port 2 bit 0.
ICB — Input Capture B.
P2.1 — Port 2 bit 1.
OCD — Output Compare D.
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.
