Internal Main Oscillator Trim Register
This register is used to manually center the Internal Main Oscillator’s (IMO) output to a target frequency.
It is strongly recommended that you do not alter this register’s values except to load factory trim settings when
changing IMO range.
When changing ranges, the new trim value for this range must be read from Flash using a Table Read operation. The new
value must be written at the lower frequency range. That is, when moving to a higher frequency range, change the IMO_TR
value and then change the range (SLIMO[1:0] in CPU_SCR1). When moving to a lower frequency, change the range first and
then update IMO_TR.
For additional information, refer to the
Register Definitions on page 64
in the Internal Main Oscillator chapter.
7:0
Trim[7:0]
