Bit 3: Receive FIFO Overflow Interrupt Enable (RFOVFIE) If this bit is set, the interrupt is enabled for RFOVFLS.
Bit 2: Receive Queue Overflow Interrupt Enable (RQVFIE) If this bit is set, the interrupt is enabled for
RQOVFLS.
Bit 1: Receive Queue Crosses Low Threshold Interrupt Enable (RQLTIE) If this bit is set, the watermark
interrupt is enabled for RQLTS.
Bit 0: Receive Queue Crosses High Threshold Interrupt Enable (RQHTIE) If this bit is set, the watermark
interrupt is enabled for RQHTS.

Default
Bit 3: Receive FIFO Overflow latched Status (RFOVFLS) This bit is set if the receive FIFO overflows for the data
to be transmitted from the MAC to the SDRAM.
Bit 2: Receive Queue Overflow Latched Status (RQOVFLS) This bit is set if the receive queue has overflowed.
This register is cleared after a read.
Bit 1: Receive Queue for Connection Crossed High Threshold Latched Status (RQHTLS) This bit is set if the
receive queue crosses the high Watermark. This register is cleared after a read.
Bit 0: Receive Queue for Connection Crossed Low Threshold Latched Status (RQLTLS) This bit is set if the
receive queue crosses the low Watermark. This register is cleared after a read.
Note the bit order differences in the high/low threshold indications in SU.QCRLS and the interrupt enables in
SU.QRIE.
