continue in deep sleep. Time will be reported at 1 microsecond

resolution. This is the default, and the recommended option.

deep sleep, but time will be measured at 6.(6) microsecond

longer to run.

- "Internal 90kHz oscillator" option provides lowest deep sleep current
|
|
consumption, and does not require extra external components. However
|
|
frequency stability with respect to temperature is poor, so time may
|
|
drift in deep/light sleep modes.
|
|
- "External 32kHz crystal" provides better frequency stability, at the
|
|
expense of slightly higher (1uA) deep sleep current consumption.
|
|
- "External 32kHz oscillator" allows using 32kHz clock generated by an
|
|
external circuit. In this case, external clock signal must be connected
|
|
to 32K_XN pin. Amplitude should be <1.2V in case of sine wave signal,
|
|
and <1V in case of square wave signal. Common mode voltage should be
|
|
0.1 < Vcm < 0.5Vamp, where Vamp is the signal amplitude.

Additionally, 1nF capacitor must be connected between 32K_XP pin and

ground. 32K_XP pin can not be used as a GPIO in this case.
