Hello,
I use ST-LINK to set Option Bytes in uC ST8AF6246. IDE is IAR.
I have a trouble with Option Bit HSITRIM (Old name 16MHZTRIM0). According to uC datasheet this bit allows oscillator trimming with 3 or 4 bit resolution (One bit for sign). ST-LINK does not see this bit! How could I set this bit ? I have read out OPT3 byte, this is 0xF0, NOPT3 is 0x0F.
Does it mean that this bit (#4) is set already? Or this bit is not available in uC?
Best Regards
