Note: All bits in this register are real time.
Bit 3: Transmit FIFO Empty (TEMPTY). A real-time bit that is set high when the FIFO is empty.
Bit 2: Transmit FIFO Full (TFULL). A real-time bit that is set high when the FIFO is full.
Bit 1: Transmit FIFO Below Low Watermark Condition (TLWM). Set when the transmit 64-byte FIFO empties
beyond the low watermark as defined by the transmit low watermark bits (TLWM).
Bit 0: Transmit FIFO Not Full Condition (TNF). Set when the transmit 64-byte FIFO has at least one byte
available.
