HI my target is 32K148 ,

THIS IS A SIMPLE QUESTION THAT I HAVE NOT BEEN ABLE TO FIND THE ANSWER SEARCHING ALL SORT OF THE DOCUMENTS

 

IN MY PROJECT:

PLL CLK =160 MHZ

SYSTEM CLK (CORE) = 80MHZ

BUS CLK= 40MHZ

 

Which one of those is used to execute instruction in thumb mode?

"NOP" is a 1 cycle instruction, but what which clock is used to calculate the cycle? 

I suspect it'd be the System clk.

 

would that be right?

Thanks,
