UPF1RST:
The UPF1RST bit is used to reset the Microprocessor Cell Extract FIFO
associated with RXD1+/-. When UPF1RST is set to logic 0, the FIFO
operates normally. When UPF1RST is set to logic 1, all the FIFO is
immediately emptied and ignores writes. The FIFO remains empty and
continues to ignore writes until logic 0 is written to UPF1RST.
UPF1OVRE:
The UPF1OVRE bit enables the assertion of the INTB output due to an
overflow error condition of the Microprocessor Cell Extract FIFO associated
with RXD1+/-. When UPF1OVRE is set to logic 1, the interrupt is enabled.
