Bit 3: Transmit FIFO Overflow for Connection Interrupt Enable (TFOVFIE) If this bit is set, the watermark interrupt is enabled for TFOVFLS.

Bit 2: Transmit Queue Overflow for Connection Interrupt Enable (TQOVFIE) If this bit is set, the watermark interrupt is enabled for TQOVFLS.

Bit 1: Transmit Queue for Connection High Threshold Interrupt Enable (TQHTIE) If this bit is set, the watermark interrupt is enabled for TQHTS.

Bit 0: Transmit Queue for Connection Low Threshold Interrupt Enable (TQLTIE) If this bit is set, the watermark interrupt is enabled for TQLTS.

Bit 3: Transmit Queue FIFO Overflowed Latched Status (TFOVFLS) This bit is set if the transmit queue FIFO has overflowed. This register is cleared after a read. This FIFO is for data to be transmitted from the HDLC to be sent to the SDRAM.

Bit 2: Transmit Queue Overflow Latched Status (TQOVFLS) This bit is set if the transmit queue has overflowed. This register is cleared after a read.

Bit 1: Transmit Queue for Connection Exceeded High Threshold Latched Status (TQHTLS) This bit is set if the transmit queue crosses the High Watermark. This register is cleared after a read.

Bit 0: Transmit Queue for Connection Exceeded Low Threshold Latched Status (TQLTLS) This bit is set if the transmit queue crosses the Low Watermark. This register is cleared after a read.
