Home — Quadrature Decoder 0, HOME input
TA3 — Timer A, Channel 3
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 prescaler_clock
signal (see Part 6.5.7 CLKO Select Register, SIM_CLKOSR).
In the 56F8323, the default state after reset is HOME0.
In the 56F8123, 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.

SPI 0 Master Out/Slave In — This serial data pin is an output from a
master device and an input to a slave device. The master device
places data on the MOSI line a half-cycle before the clock edge the
slave device uses to latch the data.
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is MOSI0.
