Bit 0: Transmit FIFO Data Packet End (TDPE). When 0, the transmit FIFO data is not a packet end. When 1, the
transmit FIFO data is a packet end. This bit should be written before the last byte of the packet is written into
TH256FDR2.

Note: When read, the value of these bits is always zero.
Bits 7 to 0: Transmit FIFO Data (TFD[7:0]). These eight bits are the packet data to be stored in the transmit
FIFO. TFD[7] is the MSB, and TFD[0] is the LSB. If bit reordering is disabled, TFD[0] is the first bit transmitted, and
TFD[7] is the last bit transmitted. If bit reordering is enabled, TFD[7] is the first bit transmitted, and TFD[0] is the
last bit transmitted.
