ON_OFF input is a 1.5V-level direct hardware connection to the internal Finite State Machine. The RTC clock must be on and stable for this control to be functional. Minimum on pulse duration is two RTC ticks, about 63 µs Minimum inter-pulse interval is one second. Minimum off duration is two RTC ticks, about 63 µs. Figure 1 gives a broad guideline for pulse waveforms that is achievable in most applications.
