UPF2RST:
The UPF2RST bit is used to reset the Microprocessor Cell Extract FIFO
associated with RXD2+/-. When UPF2RST is set to logic 0, the FIFO
operates normally. When UPF2RST 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 UPF2RST.
UPF2OVRE:
The UPF2OVRE bit enables the assertion of the INTB output due to an
overflow error condition of the Microprocessor Cell Extract FIFO associated
with RXD2+/-. When UPF2OVRE is set to logic 1, the interrupt is enabled.
