TC1 — Timer C, Channel 1
Receive Data — SCI0 receive data input
Port C GPIO — This GPIO pin can be individually programmed as an
input or output pin.
After reset, the default state is TC1.

External Interrupt Request A — The IRQA input is an asynchronous
external interrupt request during Stop and Wait mode operation.
During other operating modes, it is a synchronized external interrupt
request which indicates an external device is requesting service. It
can be programmed to be level-sensitive or negative-edge-triggered.
VPP — This pin is used for Flash debugging purposes.

Reset — This input is a direct hardware reset on the processor. When
RESET is asserted low, the hybrid controller is initialized and placed
in the reset state. A Schmitt trigger input is used for noise immunity.
The internal reset signal will be deasserted synchronous with the
internal clocks after a fixed number of internal clocks.
To ensure complete hardware reset, RESET and TRST should be
asserted together. The only exception occurs in a debugging
environment when a hardware DSP reset is required and it is
necessary not to reset the JTAG/EOnCE module. In this case, assert
RESET, but do not assert TRST.
