Output Sequence
<Example>
The clocks can be stopped when only BEEP-Amp and Speaker-Amp are operating. However ALC2 must be
disabled.
(1) ALC2 Disable: ALC2 bit =
“
0
”
(2) Power Up BEEP-Amp and Speaker-Amp: PMBP bit = PMSPK bit =
“
0
”
→
“
1
”
(3) Disable the path of
“
ALC2
SPK-Amp
”
: ALC2S bit =
“
0
”
Enable the path of
“
BEEP
SPK-Amp
”
: BEEPS bit =
“
0
”
→
“
1
”
(4) Exit the power-save-mode of Speaker-Amp: SPPS bit =
“
0
”
→
“
1
”
“

”
time depends on the time constant of external resistor and capacitor connected to BEEP pin. If
Speaker-Amp output is enabled before input of BEEP-Amp becomes stable, pop noise may occur.
e.g. R=20k, C=0.1
μ
F: Recommended wait time is more than 5
τ
= 10ms.
(5) Enter the power-save-mode of Speaker-Amp: SPPS bit =
“
1
”
→
“
0
”
(6) Power Down BEEP-Amp and Speaker-Amp: PMBP bit = PMSPK bit =
“
1
”
→
“
0
”
(7) Disable the path of
“
BEEP
SPK-Amp
”
: BEEPS bit =
“
1
”
→
“
