Note 34. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMSPL=PMSPR=PMLO =
PMHPL = PMHPR = PMHPC = PMVCM = PMPLL = MCKO = PMMIN = PMMP = M/S bits = “1”. MPWR
pin outputs 0mA.
AVDD=12mA(typ.), DVDD=3mA(typ.), TVDD=1.7mA(typ.).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=11mA(typ.), DVDD=2.5mA(typ.),
TVDD=0.03mA(typ.).
Note 35. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN =HPMTN bits
= “1”
Note 36. PMADL = PMADR = PMDAC = PMSPL = PMSPR = PMLO = PMVCM = PMPLL = PMMIN = SPPSN bits =
“1”
Note 37. PMADL = PMADR = PMDAC = PMVCM = PMPLL = PMMIN = SPPSN bits = “1”, PMSPL bit or PMSPR bit
= “1”
Note 38. All digital input pins are held TVDD or VSS3.
