Notes 1: The detected voltage (VRST) is defined as the voltage when reset occurs when the supply voltage (VDD) is falling.
2: After the SVDE instruction is executed, the voltage drop detectin circuit is valid at power down mode.
3: The detection time (TRST) is defined as the time until reset occurs when the supply voltage (VDD) is falling to [VRST–0.1 V].
