    Hi! Did you read Users Guide (slau144), Basic Clock Module chapter? Searching " oscillator fault" through whole document helps too. Also msp430x1 series documentation (slaa081) have additional clues about how oscfault detection works.

    [edit] there's FAQ page about oscfault reasons, too

    Hi

    Thank you for response.
    I forgot to explain about section about this. It is description about Flash as below.
    **************
    If a clock failure is detected during a write or erase operation, the operation is aborted, the FAIL flag is set,
    and the result of the operation is unpredictable.
    **************
    We would like to know the condition to detect this event.
    Best regards.

    >We would like to know the condition to detect this event.
    Well, by checking FAIL flag bit in the FCTL3 register!
    You had to read Flash Memory Controller documentation further, including "Flash Memory Controller registers" part.
