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
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
Have you studied the datasheet?
Have you visited the Nuvoton website and looked at their Application Notes, examples, etc?
Have you googled?
yes sir, nuvoton Cortex M4 , can you help about that???
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
