The pulse length is equal to ({FSLENHI,FSLEN} + 1) receive clock periods. Thus, if {FSLENHI,FSLEN} is zero, the Receive
Frame Sync signal is generated during one receive clock period.
This field defines the number of data words to be received after each transfer start, which is equal to (DATNB + 1).
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.
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.
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.
