Hiii i have use ARM cortex M4(M453VE6AE) I want logic /code about to PLL disable & enable.1) how to reduce current below 1mA without applying power down mode .2) How to disable PLL clock & enable HIRC clock after that function(in this function one condition is check and hold for 5sec counter) is execute after that disable HIRC clock and enable PLL clock
There is no PLL in the Cortex-M4!
The PLL is proprietary IP from the chip maker - Nuvoton, in this case.
See Fig 5.1-1 in the datasheet:
So this has nothing to do with ARM - you need to go to Nuvoton

yes sir, nuvoton Cortex M4 , can you help about that???
Have you studied the datasheet?
Have you visited the Nuvoton website and looked at their Application Notes, examples, etc?
Have you googled?
Dear sir
i already studied datasheet & i also studied application notes & example on nuvoton site, but my concepts not clear so i am asking questions
