Note 23. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD(typ).
Note 24. Maximum Input Voltage is proportional to AVDD voltage. Vin = (AUXIN+) − (AUXIN−) = 0.6 x AVDD(typ).
Note 25. PR0-6 bits = all “0”, PMMIC=PMMO=PMSPK=PMHPL=PMHPR=PMBPM=PMAUX=PMLIN= “1”.
AVDD=10mA (typ.), DVDD=5mA (typ.).
Note 26. PR0-6 bits = all “0”, PMMIC=PMMO=PMHPL=PMHPR=PMBPM=PMAUX=PMLIN= “1”, PMSPK= “0”.
Note 27. PR0-6 bits = all “0”, PMMIC=PMMO=PMSPK=PMBPM=PMAUX=PMLIN= “1”, PMHPL=PMHPR= “0”.
Note 28. All digital input pins are fixed to DVDD or DVSS. When the voltage difference among AVDD, DVDD, HVDD
and TSVDD is larger than 0.3V, the power supply current at power down mode increases.
