Note 1:

In this instance, refers specifically to the INTRC clock source.

Includes both the INTOSC 8 MHz source and postscaler derived frequencies.

Two-Speed Start-up is covered in greater detail in Section 19.3 “Two-Speed Start-up”.

Execution continues during the INTOSC stabilization period.

Required delay when waking from Sleep and all Idle modes. This delay runs concurrently with any other

required delays (see Section 3.3 “Idle Modes”).
