Home — Quadrature Decoder 1, HOME input
TB3 — Timer B, Channel 3
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. See Part 6.5.8 for
details.
Port C GPIO — This GPIO pin can be individually programmed
as input or output pin.
In the 56F8345, the default state after reset is HOME1.
In the 56F8145, the default state is not one of the functions
offered and must be reconfigured.
To deactivate the internal pull-up resistor, clear bit 3 in the
GPIOC_PUR register.

PWMA0 - 5 — These are six PWMA output pins.

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 56F8345, these pins default to ISA functionality.
In the 56F8145, 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.
