Note 22. Output voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 23. PLL Master Mode (MCKI=12.288MHz) and PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL =
MCKO = PMMIN = M/S = PMMICL = PMMICR bits = “1”.
AVDD=9mA(typ), DVDD=3mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=6mA(typ), DVDD=2mA(typ).
Note 24. PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN bits = “1” and PMSPK bit = “0”.
Note 25. PMDAC = PMLO = PMSPK = PMVCM = PMPLL = PMMIN bits = “1” and PMHPL = PMHPR bits = “0”.
Note 26. All digital input pins are fixed to DVDD or DVSS.
