CURTRIM
• UPDATED: Current Trim Value Updated
This field toggles each time the tuning procedure completes.
• LOCKLOST: Lock Lost
This field indicates that the current count is outside RCFASTCFG.LOCKMARGIN from the theoretical count. It is updated after
each tuning procedure.
• LOCK: Lock
This field indicates that the current count is within RCFASTCFG.LOCKMARGIN of the theoretical count. It is updated after each
tuning procedure.
• SIGN: Sign of Current Count Error
This field returns the sign of the current difference between the current count and the theoretical count. It is updated after each
tuning procedure.
• CNTERR: Current Count Error
This field returns the current absolute difference between the current count and the theoretical count. It is updated after each
tuning procedure.
• CURTRIM: Current Trim Value
This field returns the current trim value used by the RCFAST oscillator. It is updated after each tuning procedure.
