State
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 pull-up resistor, clear bit 6 of the
GPIOC_PUR register.
Home — Quadrature Decoder 0, HOME input
TA3 — Timer A ,Channel 3
Port C GPIO — This GPIO pin can be individually
programmed as an input or output pin.
After reset, the default state is HOME0.
To deactivate the internal pull-up resister, clear bit 7 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 pull-up resistor, clear bit 4 in the
GPIOE_PUR register.
