Introduction

Power manager interface for the 64XX/14xx.

This module defines the power resources, constraints, events, sleep states and transition latencies for 64XX.

A reference power policy is provided which can transition the MCU from the active state to one of two sleep states: Low-Power Deep Sleep (LPDS) or Sleep. The policy looks at the estimated idle time remaining, and the active constraints, and determine which sleep state to transition to. The policy will give first preference to choosing LPDS, but if that is not appropriate (e.g., not enough idle time), it will choose Sleep.
