Note 16. When PLL Master Mode (MCKI=12MHz), PMADC=PMDAC=PMPFIL=PMSL=PMVCM=PMPLL
=PMBP=PMMP=M/S=SLPSN bits = “1” and LOSEL bit = “0”. In this case, the MPWR pin
outputs 0mA. AVDD= 4.9mA (typ), DVDD= 1.5mA (typ), TVDD= 0.2mA (typ).
Note 17. When EXT Slave Mode (PMPLL=M/S bits =“0”), PMADC =PMDAC=PMSL=PMVCM=PMBP
=PMMP=SLPSN bits = “1” and PMPFIL = LOSEL bits = “0”. In this case, the MPWR pin outputs
0mA. AVDD= 4.6mA (typ), DVDD= 1.0mA (typ), TVDD= 0.02mA (typ).
Note 18. All digital input pins are fixed to TVDD or VSS2.
