Description
amplifier start enable (clear power-on reset flag D7 of DB2)
Description
regulator 4 output voltage control; see
regulator 3 (mechanical digital) control
regulator 1 output voltage control; see
soft mute all amplifier channels (mute delay 20 ms)
hard mute all amplifier channels (mute delay 0.4 ms)
0 = amplifier off; pin DIAG remains LOW
1 = amplifier on; when power-on occurs, bit D7 of DB2 is reset and
pin DIAG is released
0 = regulator 3 off
1 = regulator 3 on
0 = mute off
1 = mute on
0 = mute off
1 = mute on
