Bit 7: Receive FIFO Overrun Latched (ROVRL). This latched status bit is set to 1 each time the receive FIFO
overruns. ROVRL is cleared when the host processor writes a 1 to it and is not set again until another overrun
occurs (i.e., the FIFO has been read from and then allowed to fill up again). When ROVRL is set, it can cause a
hardware interrupt to occur if the ROVRIE bit in the
both set to 1. The interrupt is cleared when this bit is cleared or one or both of the interrupt-enable bits are cleared.

Bit 0: Transmit Packet-End Interrupt Enable (TENDIE). This bit enables an interrupt if the TENDL bit in the
HSRL
Bit 1: Transmit FIFO Underrun Interrupt Enable (TUDRIE). This bit enables an interrupt if the TUDRL bit in the
HSRL
Bit 2: Transmit FIFO Low Watermark Interrupt Enable (TLWMIE). This bit enables an interrupt if the TLWML bit
in the
Bit 3: Receive FIFO High Watermark Interrupt Enable (RHWMIE). This bit enables an interrupt if the RHWML bit
in the
Bit 4: Receive Abort Sequence Detected Interrupt Enable (RABTIE). This bit enables an interrupt if the RABTL
bit in the
Bit 5: Receive Packet Start Interrupt Enable (RPSIE). This bit enables an interrupt if the RPSL bit in the
register is set.
Bit 6: Receive Packet-End Interrupt Enable (RPEIE). This bit enables an interrupt if the RPEL bit in the
register is set.
Bit 7: Receive FIFO Overrun Interrupt Enable (ROVRIE). This bit enables an interrupt if the ROVRL bit in the
