Index — Quadrature Decoder 0, INDEX input
TA2 — Timer A, Channel 2
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is INDEX0.
To deactivate the internal pullup resistor, clear bit 6 of the
GPIOC_PUR register.

SPI 0 Serial Clock — In the master mode, this pin serves as an
output, clocking slaved listeners. In slave mode, this pin serves as
the data clock input.
Port E GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is SCLK0.
To deactivate the internal pullup resistor, clear bit 4 in the
GPIOE_PUR register.
