CONTROL PIN CHARACTERISTICS (Cont’d)
Figure 98. RESET pin protection when LVD is enabled.
Figure 99. RESET pin protection when LVD is disabled.
Note 1:
Note 2: When the LVD is enabled, it is recommended not to connect a pull-up resistor or capacitor. A 10nF pull-down
capacitor is required to filter noise on the reset line.
Note 3: In case a capacitive power supply is used, it is recommended to connect a 1MΩ pull-down resistor to the RESET
pin to discharge any residual voltage induced by the capacitive effect of the power supply (this will add 5µA to the power
consumption of the MCU).
Note 4: Tips when using the LVD:
Note 5: Please refer to “Illegal Opcode Reset” on page 128 for more details on illegal opcode reset conditions.

AN2017. If this cannot be done, it is recommended to put a 100nF + 1MΩ pull-down on the RESET pin.
In most cases, steps 1 and 2 above are sufficient for a robust solution. Otherwise: replace 10nF pull-down on the
RESET pin with a 5µF to 20µF capacitor.”
