Tri-stated

SPI 1 Master Out/Slave In — This serial data pin is an

output from a master device and an input to a slave device.

The master device places data on the MOSI line a

half-cycle before the clock edge the slave device uses to

latch the data. To activate the SPI function, set the

PHSB_ALT bit in the SIM_GPS register. For details, see

Section 6.5.8.

Input

Port C GPIO — This GPIO pin can be individually

programmed as an input or output pin.

After reset, the default state is PHASEB1.

To deactivate the internal pull-up resistor, clear bit 1 in the

GPIOC_PUR register.

Input

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 Section 6.5.8.

After reset, the default state is INDEX1.

To deactivate the internal pull-up resistor, clear bit 2 in the

GPIOC_PUR register.
