Fifofull IRQ source
Goes high when FIFO is full.
/Fifoempty IRQ source
Goes low when FIFO is empty
Goes high when an overrun error occurred. Writing a 1 clears flag and FIFO
FIFO filling method (Buffered mode only):
0
1
FIFO filling status/control (Buffered mode only):
Goes high when FIFO is being filled (sync word has been detected)
Writing ‘1’ clears the bit and waits for a new sync word (if Fifo_overrun_clr=0)
If Fifo_fill_method = ‘0’: (d)
Automatically starts when a sync word is detected (d)
Manually controlled by Fifo_fill
