SPI 1 Master In/Slave Out — This serial data pin is an input to a
master device and 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. See Part 6.5.8 for
details.
Port C GPIO — This GPIO pin can be individually programmed
as an input or output pin.
In the 56F8345, the default state after reset is INDEX1.
In the 56F8145, the default state is not one of the functions
offered and must be reconfigured.
To deactivate the internal pull-up resistor, clear bit 2 in the
GPIOC_PUR register.
