• DATNB: Data Number per Frame
This field defines the number of data words to be received after each transfer start, which is equal to (DATNB + 1).
• MSBF: Most Significant Bit First
1: The most significant bit of the data register is sampled first in the bit stream.
0: The lowest significant bit of the data register is sampled first in the bit stream.
• LOOP: Loop Mode
1: RX_DATA is driven by TX_DATA, RX_FRAME_SYNC is driven by TX_FRAME_SYNC and TX_CLOCK drives RX_CLOCK.
0: Normal operating mode.
• DATLEN: Data Length
The bit stream contains (DATLEN + 1) data bits.
This field also defines the transfer size performed by the Peripheral DMA Controller assigned to the receiver.
