falling leading edge.
Description
Receiver-driven mode selection bit (SPI master mode only). Clear this bit to initiate
transactions when transmit data is available. Set this bit to initiate transactions when the
receive buffer (FIFO or DMA) has space.
Set this bit to put the SPI in master mode, clear this bit to put the SPI in slave mode.
This bit controls behavior on a transmit buffer underrun condition in slave mode. Clear
this bit to send the BUSY token (0xFF) and set this bit to repeat the last byte. Changes to
this bit take effect when the transmit FIFO is empty and the transmit serializer is idle.
This bit specifies the bit order in which SPI data is transmitted and received.
Clock polarity configuration: clear this bit for a rising leading edge and set this bit for a
