MISO
(GPIOF6)
86
Input/Output
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 F GPIO—This General Purpose I/O (GPIO) pin can be individually
programmed as input or output.
After reset, the default state is MISO.
SS
(GPIOF7)
87
Input
Input/Output
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 F GPIO—This General Purpose I/O (GPIO) pin can be individually
programmed as input or output.
After reset, the default state is SS.
TXD0
(SCLK0)
97
Output
Input/Output
Transmit Data (TXD0)—transmit data output
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.
After reset, the default state is SCI output.
RXD0
(MOSI0)
96
Input
Input/Output
Receive Data (RXD0)— receive data input
SPI 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 one half-cycle before the clock edge the slave device uses to latch the
data.
After reset, the default state is SCI input.
TXD1
(MISO0)
93
Output
Input/Output
Transmit Data (TXD1)—transmit data output
SPI 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.
After reset, the default state is SCI output.
RXD1
(SS0)
92
Input
(Schmitt)
Input
Receive Data (RXD1)— receive data input
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.
After reset, the default state is SCI input.
