2 Low-Power Features in PMCU

The power management and clock unit (PMCU) provides all power, clocking, reset, and system control services for the device, which is the key peripheral that influences the low-power performance. The following sections help users better understand this peripheral to implement the strategies in Section 3 easily. This section describes the low-power related features and attentions in PMCU. For other features, detailed peripheral description, and register control, refer to the technical reference manual.
