The video is perfect, thank you! I'm using custom board with SAMD21J17D and want to activate XOSC (PA14 and PA15) with external crystal, but I can not initialize it. Do you have some examples with XOSC?
I made this video years ago so I don't remember all the low level details, but I am probably referring to calibration values that are set during the production of the microcontroller. The clock frequency is measured at production and if it is not within a certain tolerance there is digital adjustments that are done in NVM to adjust it. Not related to config bits. Often something similar is done to correct ADC measurements at production.
@@ForceTronics please help me with this , when I am entering sleep mode say standby mode , will the cpu execution stop. Say I am using a debugger, if I am really entering sleep mode will the debugger halt ? Note: this is a different query.
This is exactly what I was looking for. Thank you!

Can these chips be programmed with something other than an expensive debugger? 🙏
"Calibration values stored in NVM to tune the 48Mhz clock for higher frequency " is this about the configuration bits ?
