Configure the minimum edge rate
(rising or falling) of WDT pin, if
violated, WD_RESP will be triggered
00 : At least one edge occurs every
5ms
01 : At least one edge occurs every
20ms

WD_RESP

R/W
If watchdog timeout happened,
WD_RESP will guide the behavior of
AMP
00 : The Amp neither mutes nor shut
down when the watchdog is triggered.
The boost converter’s output voltage
is not affected.
01 : The Amp shuts down immediately
and the output transition is Hi-Z. The
boost converter ramps down to VBAT
then enters bypass mode.
10 : The Amp mutes according to the
configuration of VOLCTRL, instant
mute or soft mute. The boost
converter ramps down to VBAT then
enters bypass mode. (default)
11 : Signal in is multiplied by WD_RP
when watchdog timeout is happened,
instead of R_VOLUME.

Volume during watchdog timeout,
downward, 12 to
115.5dB in 0.5dB
step, (default 00101000 =
8dB)
e.g. 00000000 = 12dB
Equation : Volume = (WD_RP (DEC) x
0.5dB) + 12dB
