Phase A — Quadrature Decoder 0, PHASEA input
TA0 — Timer A, Channel 0
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 oscillator clock
signal (see Section 6.5.7 CLKO Select Register, SIM_CLKOSR).
In the 56F8322, the default state after reset is PHASEA0.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.
