Hello i am trying to understand how to control the clock of GPIO periphery for my efr32 evm board.
I have tried to use the following manual link shown bellow.
We have a main source and pre-scalers which is fed to the GPIO periphery.
I am having problem understand the table bellow., it hase 1_1 2_1 its confusing.
For GPIO what is the main sorce and what are the prescalers?
Thanks.
