Lesson 14 – nRF5x Power Management Tutorial Power modes:
- System On (mA)
- Subpower modes:
- Constant latency:
constant latency on the expense of higher current. This is done by keeping all internal voltage regulators and oscillators running.
NRF_POWER→TASKS_CONSTLAT = 1;
- HF clock always ON
- Low power (default) aka variable latency
- lower current on the expense of latency.
- The internal regulators and oscillators will be switched on/off automatically by the PMU based on the peripherals/system blocks demand.
- System Off (<1uA)
