Hey,

I would like to write simple led toggle program without any headers like HAL standard peripheral etc. So I have to write:
a. Clock initialization
b. PORTx initialization
c. what else ?

I can’t find proper informations in Cortex-M4 reference manual. How to set up right clock and init ports ?

Thanks in advance!
