Setting the Channel Bypass Enable bit (bit 3 in Register 5 -
allows the host to write data directly to the video channel through this
register, bypassing the parallel channel input port.

Audio Channel Bypass Data [7:0]
The states of these bit indicate the status of the Aux Data
FIFO as shown in the following table. Once “overrun”
(0b11) occurs, the status stays at overrun until the
register is read.
Bits

0b01
0b10
0b11
Writing a 1 to this bit resets the Aux Data FIFO to empty.
Any data in the FIFO at this time is lost.
