ISA0 — This input current status pin is used for top/bottom pulse
width correction in complementary channel operation for PWMA.
Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin.
In the 56F8323, the default state after reset is ISA0.
In the 56F8123, the default state is not one of the functions offered
and must be reconfigured.
