Description
Overflow/Underrun Interrupt Mask
When a bit is set, it enables the overflow/underrun interrupt for the
corresponding bit in the OUIR. When a bit is clear, the corresponding
bit in the OUIR will still be set on its event and cleared on read but will
not be passed on to the HIR.
Description
RMON Tx Counter Rollover
Set when the RMON Tx counter with the same index number as the bit
number has rolled over.
