A register value of 0x00 indicates no Transmit Overhead FIFO Underflow errors. Register
values of 0x01–0x43 indicate which one of the 67 Transmit Overhead FIFOs underflowed.
This register only reports the first FIFO to underflow. The subsequent underflow of another
FIFO will not be reported until this register is cleared.
A register value of 0x00 indicates no Overhead Receive FIFO Overflow errors. Register values
of 0x01–0x43 indicate which one of the 67 Receive Overhead FIFOs overflowed. This register
only reports the first FIFO to overflow. The subsequent overflow of another FIFO will not be
reported until this register is cleared.
