SPI Master In/Slave Out (MISO)—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.
Port E GPIO—This pin is a General Purpose I/O (GPIO) pin that can
be individually programmed as input or output pin.
After reset, the default state is MISO.
SPI Master Out/Slave In (MOSI)—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 that the slave device uses to latch the data.
Port E GPIO—This pin is a General Purpose I/O (GPIO) pin that can
be individually programmed as input or output pin.
After reset, the default state is MOSI.
SPI Serial Clock—In master mode, this pin serves as an output,
clocking slaved listeners. In slave mode, this pin serves as the data
clock input.
Port E GPIO—This pin is a General Purpose I/O (GPIO) pin that can
be individually programmed as an input or output pin.
After reset, the default state is SCLK.
SPI Slave Select—In master mode, this pin is used to arbitrate
multiple masters. In slave mode, this pin is used to select the slave.
Port E GPIO—This pin is a General Purpose I/O (GPIO) pin that can
be individually programmed as an input or output pin.
After reset, the default state is SS.
