SPI2_TXD
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 16, “Serial
Peripheral Interface Modules (SPI 1 and SPI 2),” and Chapter 29, “GPIO Module and I/O Multiplexer
(IOMUX),” for information on how to bring this signal to the assigned pin.
SPI2_RXD
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 16, “Serial
Peripheral Interface Modules (SPI 1 and SPI 2),” and Chapter 29, “GPIO Module and I/O Multiplexer
(IOMUX),” for information on how to bring this signal to the assigned pin.
SPI2_SS
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 16, “Serial
Peripheral Interface Modules (SPI 1 and SPI 2),” and Chapter 29, “GPIO Module and I/O Multiplexer
(IOMUX),” for information on how to bring this signal to the assigned pin.
SPI2_SCLK
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 16, “Serial
Peripheral Interface Modules (SPI 1 and SPI 2),” and Chapter 29, “GPIO Module and I/O Multiplexer
