  #lcamtuf’s #introduction to #Atmel #ARM ATSAMS70J21 #hardware bringup from a year ago. “On an 8-bit MCU, adjusting the clock is trivial; on the SAM S70, you can try some online examples, realize that they’re all wrong, and then spend several hours nose down in the 2,000 page datasheet. (...) The first revelation is that 300 MHz is the maximum clock for the processor core (HCLK), not the entire device. There is an internal bus used by the flash memory controller and other built-in peripherals, and that bus can’t run faster than 150 MHz; this fact is helpfully mentioned on page 1852 of the spec.” #microcontroller
