Bit Name
Transmit Transfer Initiate.
The SPI_TXCTL.TTI bit enables initiation of transmit transfers if the transmit
FIFO (SPI_TFIFO) is not empty. The bit also enables this initiation if
not zero when SPI_TXCTL.TWCEN is enabled. Enabling SPI_TXCTL.TTI pre-
vents transmit underrun errors from occurring. The SPI_TXCTL.TTI bit is valid
only when the SPI is a master.
Transmit Enable.
The SPI_TXCTL.TEN bit enables SPI transmit channel operation.
