The pulse length is equal to ({FSLENHI,FSLEN} + 1) transmit clock periods, i.e., the pulse length can range from 1 to 256
transmit clock periods. If {FSLENHI,FSLEN} is zero, the Transmit Frame Sync signal is generated during one transmit clock
period.
This field defines the number of data words to be transferred after each transfer start, which is equal to (DATNB + 1).
1: The most significant bit of the data register is shifted out first in the bit stream.
0: The lowest significant bit of the data register is shifted out first in the bit stream.
This bit defines the level driven on the TX_DATA pin while out of transmission.
Note that if the pin is defined as multi-drive by the I/O Controller, the pin is enabled only if the TX_DATA output is one.
1: The level driven on the TX_DATA pin while out of transmission is one.
0: The level driven on the TX_DATA pin while out of transmission is zero.
The bit stream contains (DATLEN + 1) data bits.
This field also defines the transfer size performed by the Peripheral DMA Controller assigned to the transmitter.
