I have an osbdm board,and i find if i use the qd4 internal oscillator,the frequency is changed.I checked the qd4 datasheet,and i knew the ICSTRM and ICSSC register located at 0xffaf and 0xffae is erased ,all of them are 0xff,but i checked the "programm trim data upon application load",so i think the osbdm erased the ICSTRM and ICSSC but not programmed the new actual trim value.
please tell me why ,and how can i use the internal oscillator and trim it????
