UPF1OVRI:
The UPF1OVRI bit indicates an interrupt due to overflow error condition of the
Microprocessor Cell Extract FIFO associated with RXD1+/-. Generally, the
UPF1OVRI status bit should never be asserted; its assertion would indicate
that the flow control protocol is being ignored. The UPF1OVRI bit is reset
immediately after a read to this register.
