Initialization string for a bridged output stage with its own BBM:
sub-address value
20h
00000000b Un-freeze registers. System starts in mute so the instruction sequence is not
important.
21h
11000000b Turn off de-emphasis and DC blocking filters. Turn on droop correction filter.
22h
00010000b 48kHz sampling rate.
23h
01000011b MCK will be 48kHz * 256 = 12.288MHz. Sync Reset is on and it will trigger a
hard-mute.

Always set Saturation Clamp to these values.
3Dh
10000000b Turn on PGC.
71h
10111010b Stagger switching frequencies.
72h
11011100b Stagger switching frequencies.
73h
00000000b Turn of Startup Burst if not needed.
74h
00000000b YSN = 0, HPO = 0, TST_EN output is low.
75h
00h
Test.
76h
10000110b Enable Delay compensation. Use B-cal for bridged output. Enable automatic
DC calibration. Normal HMUTE operation. No BBM.

Test.
7Ch
00110000b Normal OV/UV operation. SLEEP_OUT = high.
7Dh
00011110b All channels use B-cal for bridged output.
To Un-mute a bridged output stage:
sub-address value
77h
01111000b Prevent switching until after automatic DC calibration is complete.
2Ch
00000000b Remove Hard-Mute to begin automatic DC calibration.
<If PGC is on, wait 4 seconds for automatic DC calibration. If PGC is off, wait 1 second for calibration.>
77h
00000000b Begin switching.
