Note 23. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
PMVCM = PMPLL = MCKO = PMMIN = PMMP = M/S bits = “1”. MPWR pin outputs 0mA.
AVDD=11mA(typ), DVDD=3mA(typ), TVDD1+TVDD2=2mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=10mA(typ), DVDD=3mA(typ),
TVDD1+TVDD2=0.03mA(typ).
Note 24. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN bits = “1”.
Note 25. All digital input pins are fixed to each supply pin (TVDD1, TVDD2 or TSVDD) or (VSS2 or VSS3).
