PWMA1 — This is one of six PWMA output pins.
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 PWMA1.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.

PWMA2 — This is one of six PWMA output pins.
SPI 1 Slave Select — SS1 is used in slave mode to indicate to the
SPI module that the current transfer is to be received.

input or output pin.
In the 56F8322, the default state after reset is PWMA2.

PWMA3 — This is one of six PWMA output pins.
SPI 1 Master In/Slave Out — This serial data pin is an input to a
master device and an output from a slave device. The MISO line of a
slave device is placed in the high-impedance state if the slave device
is not selected. The slave device places data on the MISO line a
half-cycle before the clock edge the master 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 PWMA3.
In the 56F8122, the default state is not one of the functions offered
and must be reconfigured.
