Hello,
according to AN12085 each low power mode (including system idle) includes changing the clock frequencies
Kind regards,
Stefan

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
1) Is there a way to keep clock settings with their normal "run" frequency (e.g. SPI is still clocked with 66 MHz, FlexSPI 132 MHz) and just put the core in a wait for interrupt / power-down state?
-- No, I'm afraid not.
2) so should we never use any low power mode or should we just put the code which switches to low power mode into internal RAM?
-- The above statement is used to help the developers to design more robust code to enter any low power mode, as it says, it'd better remap the clock change code or function to the On-chip RAM to run.
Have a great day,
TIC
