A register value of 0x00 indicates no Transmit Payload FIFO Underflow errors. Register
values of 0x01–0x1C indicate which one of the 28 Transmit Payload 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 Payload Receive FIFO Overflow errors. Register values
of 0x01–0x1C indicate which one of the 28 Receive Payload 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.
A register value of 0x00 indicates no Receive Payload FIFO Underflow errors. Register values
of 0x0–0x1C indicate which one of the 28 Receive Payload 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 transmit Overhead Transmit FIFO Overflow errors.
Register values of 0x01–0x43 indicate which one of the 67 Transmit 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.
