Index1 — Quadrature Decoder 1, INDEX input
TB2 — Timer B, Channel 2
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. To activate the SPI function, set
the INDEX_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 an input or output pin.
In the 56F8357, the default state after reset is INDEX1.
In the 56F8157, the default state is not one of the functions
offered and must be reconfigured.
To deactivate the internal pull-up resistor, clear bit 2 in the
GPIOC_PUR register.

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 an input or output pin.
In the 56F8357, the default state after reset is HOME1.
In the 56F8157, 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.
