DESCRIPTION
D7 regulator 5 output voltage control
D6 ^{(see Table 2)}
D5
D4
D3 SW2 control
0 = SW2 off
1 = SW2 on
D2 SW1 control
0 = SW1 off
1 = SW1 on
D1 AC- or DC-load detection switch
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
D0 amplifier start enable (clear power-on reset
flag; D7 of DB2)
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
