POWER-DOWN Mode
1.3.7
All the internal circuits are entered the stop state.
Power down operation has special power off sequence as below picture.
POWER DOWN MODE
ENTER
END
STOP1 or STOP2
STOP1
FM.MR[7:0] = TRIM MODE
SCU.VDCCON[25]=STOP1
FM.MR[7:0] = 0x00
FM.MR[7:0] = TRIM MODE
SCU.VDCCON[25]=STOP2
FM.MR[7:0] = 0x00
STOP2
SCU.LVDCON[0]=LVD_DISABLE
SETUP WAKE UP SOURCE
SCU.CSCR=Enable All Clock
Wait for stabilizing
SCU.SCCR=LSI
SCU.CSCR=0x20 (only LSI enable)
SCB.SCR[2]*=1
WFI
(ENTER POWER DOWN)
Wait for WAKE UP signal
WAKE UP DEFAULT CLOCK = LSI
RECOVER CLOCK SOURCE
SCU.SMR[9] ?
Disable
Enable
LSI CLK STOP
SCB.SCR[2]*=1
