Index — Quadrature Decoder 0, INDEX input
TA2 — Timer A, Channel 2
Port B GPIO — This GPIO pin can be individually programmed as an
input or output pin.
Clock Output - can be used to monitor the internal SYS_CLK signal
(see Section 6.5.7 CLKO Select Register, SIM_CLKOSR).
In the 56F8322, the default state after reset is INDEX0.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.

SPI 0 Serial Clock — In the master mode, this pin serves as an
output, clocking slaved listeners. In slave mode, this pin serves as the
data clock input. A Schmitt trigger input is used for noise immunity.
Port B GPIO — This GPIO pin can be individually programmed as an
input or output pin.
After reset, the default state is SCLK0.
