Headphone-Amp goes to mute state after the transition time set by PTS1-0 and MOFF1 bits.
(10)Headphone-Amp power-down: PMHPL/R bits = “1” Æ “0”
Headphone-Amp is powered-down immediately.
(11)Power-down of Charge Pump, VCOMA and HP-Amp Mixer & Selector (and the internal clock oscillator in case of
OSCN bit = “0”): PMCP = PMMHL = PMMHR = PMOSC = PMVCMA bits = “1” Æ “0”
The PVEE pin goes 0V according to the time constant of the capacitor at the PVEE pin and the internal resistor. The
internal resistor is typ. 17.5kΩ. Charge Pump circuit can be powered-up during this period.
