SW2 control
SW1 control
AC- or DC-load detection switch
amplier start enable (clear power-on reset
ag; D7 of DB2)
0 = SW2 off
1 = SW2 on
0 = SW1 off
1 = SW1 on
0 = AC- or DC-load detection off; resets
DC-load detection bits and AC-load
detection peak current counter
1 = AC- or DC-load detection on
0 = amplier OFF; pin DIAG remains LOW
1 = amplier ON; when power-on occurs,
bit D7 of DB2 is reset and pin DIAG is
released
