How to generate 120 Mhz clock from 12 Mhz in K70?

[pramodk_g_]

Hi Everyone,

                              I am using TWR K70 and MQX 4.0 with CW 10.5. I need to work my board at 120 Mhz and it should be generated from 12Mhz clock source in the twr module.  How is this possible using PLL, what values we should put into corresponding registers? I have generated a code with this requirement from PE but how i can port it into my existing MQX code?

Please let me know your valuable response.

Thanks.

Pramod.

Hi,

You need to modify the BSP. Please check the document attached, this shows how to Change Default Clock Settings in Kinetis BSPs.

Have a great day,
Sol
