Data written to this register is serialized and transmitted on the data link least
significant bit first. The XFDL signals when the next data byte is required by
setting the TDLINT[x] output high (if enabled) and by setting the INT bit in the
XFDL Interrupt Status register high. When INT and/or TDLINT[x] is set, the
Transmit Data register must be written with the new data within 4 data bit periods
to prevent the occurrence of an underrun.
