Debounce on BUTTON pin
The BUTTON pin is active low. For a start/stop command detection, the voltage on the BUTTON pin must be
maintained low during 10ms. Then, a delay of 20ms is necessary before the next start/stop command.
This allow to remove wrong start/stop commands due to oscillations when using of low-cost push buttons.
NiMH pin
Pin NIMH goes high when VDD is below the NIMH threshold of 1.41V and low when VDD is above the same
threshold.
A 30mV hysteresis allow to remove NiMH pin oscillation when the VDD voltage is near the threshold.
The supply voltage on VDD pin is checked at a 1Hz rate, so the NiMH pin can switch with a delay of 1 seconds
max.
