Bit 5: Transmit FIFO Overflow Latched (TFOL). This bit is set when a transmit FIFO overflow condition occurs.
Bit 4: Transmit FIFO Underflow Latched (TFUL). This bit is set when a transmit FIFO underflow condition
occurs. An underflow condition results in a loss of data.
Bit 3: Transmit Packet End Latched (TPEL). This bit is set when an end of packet is read from the transmit FIFO.
Bit 1: Transmit FIFO Empty Latched (TFEL). This bit is set when the TFE bit transitions from 0 to 1. Note: This
bit is also set when TH256CR1.TFRST is deasserted.
Bit 0: Transmit HDLC-256 Data Available Latched (THDAL). This bit is set when the THDA bit transitions from 0
to 1. Note: This bit is also set when TH256CR1.TFRST is deasserted.

Bit 5: Transmit FIFO Overflow Interrupt Enable (TFOIE). This bit enables an interrupt if the TFOL bit is set.
Bit 4: Transmit FIFO Underflow Interrupt Enable (TFUIE). This bit enables an interrupt if the TFUL bit is set.
Bit 3: Transmit Packet End Interrupt Enable (TPEIE). This bit enables an interrupt if the TPEL bit is set.
Bit 1: Transmit FIFO Empty Interrupt Enable (TFEIE). This bit enables an interrupt if the TFEL bit is set.
Bit 0: Transmit HDLC-256 Data Available Interrupt Enable (THDAIE). This bit enables an interrupt if the THDAL
bit is set.
