SPI 0 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.
Port E GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is MOSI0.
To deactivate the internal pullup resistor, clear bit 5 in the
GPIOE_PUR register.

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 pullup 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 pullup resistor, clear bit 7 in the
GPIOE_PUR register.
