DCFIFO_KILL_DIS, HDMI Map, Address 0x1B, [2]
If the DCFIFO has to resynchronize the pointers more than once within two cycles of the FIFO, the
output of the FIFO is considered unusable and is set to zero. This feature can be disabled by
DCFIFO_KILL_DIS.

is a self clearing bit that resets the write pointer to be eight locations
Description
Does nothing
Resets write pointer to be eight locations away from read pointer (self
clearing)
allows the read and write pointer comparison to be performed after dropping
Description
Read and write pointer comparison performed after dropping the
LSBs. FIFO resynchronizes when read and write pointers come within
one LSB of each other.
Read and write pointer comparison performed after dropping two
LSBs. FIFO resynchronizes when read and write pointers come within
two LSBs of each other.
Description
FIFO output set to zero if more than one resynchronization is
necessary during two FIFO cycles
FIFO output never set to zero regardless of how many
resynchronizations occur
