FIFO full interrupt
Full interrupt status is asserted when the full interrupt condition is satisfied, when the filling level of the
FIFO (number of unread bytes in the FIFO = fifo_bytes_cnt<10:0>) is equal or higher than 1016. The
status of the full interrupt can be read back through the ffull_int bit.
Interrupt status is cleared by reading the ffull_int bit high '1' when the FIFO filling level is lower than
1016.
The full interrupt is propagated to INT pad only when it is enabled by setting bit ffull_en = ‘1’.
The behavior of the FIFO full interrupt is shown in the figures below.
