SC_SPIRXDRV
The exponential component (EXP) of the clock rate as seen in the equation: rate = 24MHz / ( 2 *
(LIN + 1) * (2^EXP) )
Receiver-driven mode selection bit (SPI master mode only). Clearing this bit will initiate trans-
actions when transmit data is available. Setting this bit will initiate transactions when the
receive buffer (FIFO or DMA) has space.
This bit must always be set to put the SPI in master mode (slave mode is not valid).
This bit controls behavior on a transmit buffer underrun condition in slave mode. Clearing this
bit will send the BUSY token (0xFF) and setting this bit will repeat the last byte. Changing this
bit will only take effect when the transmit FIFO is empty and the transmit serializer is idle.
Clearing this bit will result in the Most Significant Bit being transmitted first while setting this
bit will result in the Least Significant Bit being transmitted first.
Clock phase configuration is selected with clearing this bit for sampling on the leading (first
edge) and setting this bit for sampling on second edge.
Clock polarity configuration is selected with clearing this bit for a rising leading edge and
setting this bit for a falling leading edge.
