Note 21. PLL Master Mode (MCKI=12MHz)で、PMADL = PMADR = PMDAC =PMPFIL = PMHPL = PMHPR =
PMVCM = PMPLL = PMBP = PMMP = M/S bits = “1”、LPMIC = LPDA bits = “0”の場合です。このとき、
MPWR1 (MPWR2) pin の出力電流は 0mA です。AVDD= 7.3mA (typ), DVDD= 1.6mA (typ), TVDD= 0.3mA
(typ).
Note 22. EXT Slave Mode (PMPLL=M/S bits =“0”)、PMADL = PMADR = PMDAC = PMHPL = PMHPR = PMVCM
= PMBP = PMMP bits = “1”, PMPFIL = LPMIC = LPDA bits = “0”の場合。このとき、MPWR1 (MPWR2) pin
の出力電流は 0mA です。AVDD= 6.5mA (typ), DVDD= 1.6mA (typ), TVDD= 0.1mA (typ).
Note 23. PLL Master Mode (MCKI=12MHz)で、PMADL = PMADR = PMDAC =PMPFIL = PMSL = PMVCM =
PMPLL = PMBP = PMMP = M/S bits = “1”、LPMIC = LPDA bits = “0”の場合です。このとき、MPWR1
(MPWR2) pin の出力電流は 0mA です。AVDD= 6.5mA (typ), DVDD= 1.4mA (typ), TVDD= 0.3mA (typ).
Note 24. EXT Slave Mode (PMPLL=M/S bits =“0”)、PMADL = PMADR = PMDAC = PMSL = PMVCM = PMBP =
PMMP bits = “1”, PMPFIL = LPMIC = LPDA bits = “0”の場合。このとき、MPWR1 (MPWR2) pin の出力
電流は 0mA です。AVDD= 5.7mA (typ), DVDD= 1.4mA (typ), TVDD= 0.1mA (typ).
Note 25. 全てのディジタル入力ピンを TVDD または VSS2 に固定した時の値です。
Note 26. AVDD, DVDD, TVDD が OFF の場合。
