Input
SPI 0 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.
Port E GPIO — This GPIO pin can be individually
programmed as an input or output pin.
After reset, the default state is MISO0.
To deactivate the internal pull-up resistor, clear bit 6 in the
GPIOE_PUR register.
SPI 0 Slave Select — SS0 is used in slave mode to
indicate to the SPI module that the current transfer is to be
received.
Port E GPIO — This GPIO pin can be individually
programmed as input or output pin.
After reset, the default state is SS0.
To deactivate the internal pull-up resistor, clear bit 7 in the
GPIOE_PUR register.
Phase A1 — Quadrature Decoder 1, PHASEA input for
decoder 1.
TB0 — Timer B, Channel 0
Input
Input
SPI 1 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. To activate the SPI
function, set the PHSA_ALT bit in the SIM_GPS register.
For details, see Section 6.5.8.
Port C GPIO — This GPIO pin can be individually
programmed as an input or output pin.
After reset, the default state is PHASEA1.
To deactivate the internal pull-up resistor, clear bit 0 in the
GPIOC_PUR register.
