ESP32C3 will reset at wake-up if GPIO is received a small electrostatic pulse during
light sleep, with specific condition
- GPIO needs to be configured as input-mode only
- The pin receives a small electrostatic pulse, and reset occurs when the pulse
voltage is higher than 6 V
For GPIO set to input mode only, it is not a good practice to leave it open/floating,
The hardware design needs to controlled it with determined supply or ground voltage
is necessary.
This option provides a software workaround for this issue. Configure to isolate all
GPIO pins in sleep state.
