Power and clock management in nRF52810 is designed to
automatically ensure maximum power efficiency.
The core of the power and clock management system is the power management unit (PMU)
illustrated in Power management unit.
Figure 1. Power management unit
The PMU automatically detects which power and clock resources are required by the different
components in the system at any given time. It will then start/stop and choose operation modes
in supply regulators and clock sources, without user interaction, to achieve the lowest power
consumption possible.
