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 56F8346, the default state after reset is INDEX1.
In the 56F8146, 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 56F8346, the default state after reset is HOME1.
In the 56F8146, 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.
