LMK04828BEVM: LMK04828: PLL lock detect

Hi Derek,

Is there any other method to check whether PLL is locked in LMK04828 device.
Or the only option is to read-back RB_PLL1_LD/RB_PLL2_LD registers to know whether PLLs are locked?

Thanks.

    Hi Aleena,

    All of the GPIO pins (Status_LD1, Status_LD2, CLKin_SEL0, CLKin_SEL1, RESET/GPO) can be configured to monitor the PLL1, PLL2, or PLL1 & PLL2 lock detect. For example, Status_LD1 can be configured to read back PLL1 lock detect by configuring PLL1_LD_TYPE as an output, and PLL1_LD_MUX for PLL1 DLD.

    Regards,
