Note: FULL ON is defined as follows: The processor is not sleeping, the Core regulator and the Ring Oscillator
remain powered, and at least one block is not sleeping.
Note 37-1 The sleep states are defined in the System Sleep Control Register in the Power, Clocks and Resets
Chapter. See Table 3-10, “System Sleep Control Bit Encoding,” on page 61.
