config32 0x20 15:12 syncsel_fifoin(3:0) Selects the syncing source(s) of the FIFO input side. A ‘1’ in the bit enables the 0010
signal as a sync source. More than one sync source is permitted.
MM Bit 15: sif_sync (via config31)
MM Bit 14: Always zero
MM Bit 13: FRAME
MM Bit 12: SYNC
11:8 syncsel_fifoout(3:0) Selects the syncing source(s) of the FIFO output side. A ‘1’ in the bit enables the 0100
signal as a sync source. More than one sync source is permitted.
