    Hi Zheng,

    We need to verify the 4th bit (i.e.CLK_LOSS_STATUS_RC_CLOCK_LOSS) in the OP_RCM_CLK_LOSS_STATUS Register.

    This bit will give us the RC clock status that means status of on-chip oscillator. If this bit is logic-1 means the oscillator clock is lost, and if this bit is logic-0 that means on-chip oscillator is available.

    Hi, 

    To add to the above response from Jagadish, 

    Both bit-4 CLK_LOSS_STATUS_RC_CLOCK_LOSS

    and bit-0 CLK_LOSS_STATUS_CRYSTAL_CLOCK_LOSS

    can be checked to detect clock loss of RC-clock and Crystal clock respectively. 

    For related details, please refer to section "6.4.4 Limp Mode" in the TRM. 

    Regards,
    Nilkanth
