The power and clock management system is optimized for ultra-low power applications to provide maximum power efficiency.
The power and clock management system is shown in the following figure.
The power and clock management system automatically tracks the power and clock resources requested by components in the system at any given time. To achieve the lowest power consumption possible, the system evaluates the requests, starts and stops clock sources, and chooses the most optimal regulator operation modes.
The device start-up sequence after reset is described in RESET — Reset control.
