State
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
TA2 — Quad timer module A channel 2 input/output
XB_IN3 — Crossbar module input 3
CMP_REF— Positive input 3 of analog comparator A and B and C
After reset, the default state is GPIOC6
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
SS — SS is used in slave mode to indicate to the SPI module that
the current transfer is to be received.
TXD0 — SCI0 transmit data output or transmit/receive in single wire
operation
After reset, the default state is GPIOC7.
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
MISO — Master in/slave out. In master mode, this pin serves as the
data input. In slave mode, this pin serves as the data output. The
MISO line of a slave device is placed in the high-impedance state if
the slave device is not selected.
RXD0 — SCI0 receive data input
After reset, the default state is GPIOC8.
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
SCLK — The SPI serial clock. In master mode, this pin serves as
an output, clocking slaved listeners. In slave mode, this pin serves
as the data clock input.
XB_IN4 — Crossbar module input 4
After reset, the default state is GPIOC9.
