Regarding the core clock of the i.MX RT595

[adc_6_6]

Hello.

Could you please tell me if it's possible to change the core clock while operating on RT595?

For example, increasing the clock before performing a high-load process and then lowering it afterwards.

Thank you.

thank you for your reply.

I understand the rules.

In this case, is there a regulation regarding the interval between changing the clock and adjusting the voltage?
Additionally, how long does it take for the system to stabilize after making these changes?

Best regards

Yes, you can see the voltage and its maximum frequency on the datasheet under the general operating conditions chapter.
For the main system it is characterized a maximum of 150us but this value may vary.

Best regards,

Hello

You need to set an alternate clock to be used as main clock while you change the frequency of your clock. 
When the frequency of Core needs to change the voltage of the Core also need to be change. There is a rule in changing core frequency and voltage.
• Increasing core frequency, voltage first, then frequency.
• Decreasing core frequency, frequency first, then voltage.
