31.3.5 Interrupts
The module generates an interrupt that is configurable by the user for
either of the two conditions. If CRCISEL is ‘1’, an
interrupt is generated when the VWORD[4:0] bits make a transition from a value of ‘1’ to ‘0’. If CRCISEL is
‘0’, an interrupt will be generated when the FIFO is
empty and shifts from the shift buffer are finished.
