Input
SPI 1 Slave Select — In the master mode, this pin is used to
arbitrate multiple masters. In slave mode, this pin is used to select
the slave. To activate the SPI function, set the HOME_ALT bit in
the SIM_GPS register. For details, see Part 6.5.8.

Port C GPIO — This GPIO pin can be individually programmed as
input or output pin.
In the 56F8355, the default state after reset is HOME1.
In the 56F8155, the default state is not one of the functions offered
and must be reconfigured.

To deactivate the internal pull-up resistor, set bit 3 in the
GPIOC_PUR register.
PWMA0 - 5 — These are six PWMA outputs.
Input
ISA0 - 2 — These three input current status pins are used for
top/bottom pulse width correction in complementary channel
operation for PWMA.

Port C GPIO — These GPIO pins can be individually programmed
as input or output pins.
In the 56F8355, these pins default to ISA functionality.
In the 56F8155, the default state is not one of the functions offered
and must be reconfigured.
To deactivate the internal pull-up resistor, clear the appropriate bit
of the GPIOC_PUR register. See Part 6.5.6 for details.
