Note 26. Output voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 27. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
PMSPK = PMVCM = PMPLL = MCKO = PMMIN = PMMP = M/S bits = “1”. MPWR pin outputs 0mA.
AVDD=12mA(typ), DVDD=4mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=11mA(typ), DVDD=3mA(typ).
Note 28. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN bits = “1” and
PMSPK bit = “0”.
Note 29. PMADL = PMADR = PMDAC = PMLO = PMSPK = PMVCM = PMPLL = PMMIN bits = “1” and PMHPL =
PMHPR bits = “0”.
Note 30. All digital input pins are fixed to DVDD or DVSS.
