- Check that all recommendations related to ICCCLK and reset circuit have been applied (see caution in
Table 2
- Check that the power supply is properly decoupled (100nF + 10µF close to the MCU). Refer to AN1709
and AN2017. If this cannot be done, it is recommended to put a 100nF + 1MΩ pull-down on the RESET
pin.
- The capacitors connected on the RESET pin and also the power supply are key to avoid any startup
marginality. 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.”
