Channel B = Channel A (Bit 0 - 3)
Default = 0
Function:
Zero-Crossing Time-Out Period (Bits 4:2)
Default = 011
Function:
When this bit is set, Channel A and Channel B volume levels and muting conditions are controlled by
the Channel A volume and muting register settings, and the Channel B register settings are ignored.
When this bit is cleared, Channel A and Channel B volume and mute settings are independently con-
trolled by the A and B volume and muting bits.
These bits set the zero-crossing time-out period as shown in
Time-Out” section on page 22
