Bit
Name
Register Description: TX FIFO Out of Sequence Event:
These register bits provide status information, and indicate if out-of-sequence data has been
received. The bit position equals the port number + 8. These bits are cleared on Read.
Register Description: TX FIFO Underflow Event:
This register provides a status that a FIFO Empty situation has occurred (for example, a FIFO
under-run). The bit position equals the port number + 4. This register is cleared on Read.
Register Description: TX FIFO Overflow Event:
This register provides a status that a FIFO full situation has occurred (for example, a FIFO
overflow). The bit position equals the port number. This register is cleared on Read.
