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 individually be 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 individually be 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 individually be programmed as 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 individually be programmed as input or output pin.
After reset, the default state is SS.
ISB0-2— These three input current status pins are used for
top/bottom pulse width correction in complementary channel
operation for PWMB.
FAULTB0-3— These four Fault input pins are used for
disabling selected PWMB outputs in cases where fault
conditions originate off-chip.
