Note: • These characteristics apply when noise is not superimposed on the power supply.
Note 1. When the CPU is in a mode other than software standby mode, when the CPU transits to software standby mode with the
FHSSBYCR.SOFTCUT[2] bit set to 0.
Note 2. When the CPU transits to software standby mode with the FHSSBYCR.SOFTCUT[2] bit set to 1.
Note 3. # in the symbol Vdet0_# denotes the value of the OFS1.VDSEL[1:0] bits.
Note 4. # in the symbol Vdet1_# denotes the value of the LVDLVLR.LVD1LVL[3:0] bits.
