PWMA4 — This is one of six PWMA output pins.
SPI 1 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 A GPIO — This GPIO pin can be individually programmed as an
input or output pin.
In the 56F8322, the default state after reset is PWMA4.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.

PWMA5 — This is one of six PWMA output pins.
SPI 1 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 A GPIO — This GPIO pin can be individually programmed as an
input or output pin.
In the 56F8322, the default state after reset is PWMA5.
In the 56F8122, the default state is not one of the functions offered

FAULTA0 — This fault input pin is used for disabling selected PWMA
outputs in cases where fault conditions originate off-chip.
Port A GPIO — This GPIO pin can be individually programmed as an
input or output pin.
In the 56F8322, the default state after reset is FAULTA0.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.
