SPI2 Master TxData Output—This signal is multiplexed with a GPI/O pin however it does
show up as a primary or alternative signal in the signal multiplex scheme table. Refer to
Chapter 18, "Serial Peripheral Interface Modules (SPI 1 and SPI 2)," and Chapter 32,
"GPIO Module and I/O Multiplexer (IOMUX)," for information on how to bring this signal
to the assigned pin.
SPI2 master RxData input—This signal is multiplexed with a GPI/O pin however it does
show up as a primary or alternative signal in the signal multiplex scheme table. Refer to
Chapter 18, "Serial Peripheral Interface Modules (SPI 1 and SPI 2)," and Chapter 32,
"GPIO Module and I/O Multiplexer (IOMUX)," for information on how to bring this signal
to the assigned pin.
SPI2 Slave Select—This signal is multiplexed with a GPI/O pin, however it does show up
as a primary or alternative signal in the signal multiplex scheme table. Refer to
Chapter 18, "Serial Peripheral Interface Modules (SPI 1 and SPI 2)," and Chapter 32,
"GPIO Module and I/O Multiplexer (IOMUX)," for information on how to bring this signal
to the assigned pin.
SPI2 Serial Clock—This signal is multiplexed with a GPI/O pin however it does show up
as a primary or alternative signal in the signal multiplex scheme table. Refer to
Chapter 18, "Serial Peripheral Interface Modules (SPI 1 and SPI 2)," and Chapter 32,
"GPIO Module and I/O Multiplexer (IOMUX)," for information on how to bring this signal
to the assigned pin.
