RX210 Group 5. Electrical Characteristics
5.8 Power-on Reset Circuit and Voltage Detection Circuit Characteristics
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 and deep software standby modes, when the CPU transits to software
standby mode with the FHSSBYCR.SOFTCUT[2] bit set to 0, or when the CPU transits to deep software standby mode with the
DPSBYCR.DEEPCUT1 bit set to 0.
Note 2. When the CPU transits to software standby mode with the FHSSBYCR.SOFTCUT[2] bit set to 1 or when the CPU transits to
deep software standby mode with the DPSBYCR.DEEPCUT1 bit set to 1.
Note 3. # in the symbol Vdet0_# denotes the value of the LDSEL[1:0] bits.
Note 4. # in the symbol Vdet1_# denotes the value of the LVDLVLR.LVD1LVL[3:0] bits.
