I am using lpc54114. I found in SDK, when we use
CLOCK_SetupFROClocking(12000000)
It will turn off FRO_HF.
I wonder if we turn on FRO_HF, the FRO_12M will be turned off of not?
Hello Da Chen,
"if we turn on FRO_HF, the FRO_12M will be turned off of not?"
-> Yes, it will turned off. Only can choose one of them as input:
Hope it helps,
Have a great day,
TIC

Hi Alice_Yang,
Thanks for your replying.
But how can you tell the fro working status just from the picture you provided? MAINCLKSELA is just for choosing clock source, right? Although the fro_hf is chosen as the input? Can't the fro_12m still running?

Hello Da Chen,
Sorry I misunderstood your meaning.
Yes, the FRO_12M still running, there is no register that disable this clock in LPC54114.
Hope it helps,
