Functional description

Entered from any state when

the MCU enters Stop mode

• During exits from VLPS when the MCG is in PEE mode,

the MCG will reset to PBE clock mode and the C1[CLKS]

and S[CLKST] will automatically be set to 2'b10.

• If entering Normal Stop mode when the MCG is in PEE

mode with PLLSTEN=0, the MCG will reset to PBE clock

mode and C1[CLKS] and S[CLKST] will automatically be

set to 2'b10.

30.4.1.1 MCG modes of operation

The MCG operates in one of the following modes.

The MCG restricts transitions between modes. For the

permitted transitions, see

Figure 30-13. MCG mode state diagram

Returns to the state that was active before

the MCU entered Stop mode, unless a

reset occurs while in Stop mode.
