Schmitt

Input

Input

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 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 HOME1.

To deactivate the internal pull-up resistor, clear bit 3 in the

GPIOC_PUR register.

Input

Port C GPIO — These GPIO pins can be individually

programmed as input or output pins.

At reset, these pins default to ISA functionality.

To deactivate the internal pull-up resistor, clear the

appropriate bit of the GPIOC_PUR register. For details,

see Section 6.5.8.
