Hello,

How to disable/enable the core PLL and peripheral PLL, when it is unused, to reduce the power consumption.


Thanks.

    Hello Sudhakar,

     

    The MSS_TOPRCM:PLL_CORE_CLKCTRL and MSS_TOPRCM:PLL_PER_CLKCTRL registers contain an “IDLE” control bit; when this bit is set to 1, the PLLs will go into an Idle/Low Power mode. The PLL will activate and re-lock when this bit is set back to 0.

    Best Regards,
