56F827 Technical Data
MISO
(GPIOF6)
100
Input/Output
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)
99
Input/Output
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)
108
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)
107
Input
Input/Output
Receive Data (RXD0)
—receive data input
SPI Master Out/Slave In
—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.
TXD1
(MISO0)
106
Output
Input/Output
Transmit Data (TXD1)
—transmit data output
SPI Master In/Slave Out
—This serial data pin is an output to a master
device and an input from 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.
RXD1
(SS0)
105
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.
