FIEN[1]:
The FIFO event interrupt enable (FIEN[1]) bit controls the activation of the interrupt (INTB)
output due to a FIFO overflow or a FIFO underflow. When set to logic 1, the corresponding
pending interrupts will assert the interrupt (INTB) output. When set to logic 0, the
corresponding pending interrupts will not assert the interrupt (INTB) output.
