DEMO9RS08KA2 User's Manual
7 Internal Oscillator Trimming
The MC9RS08KA2 microcontroller features an internal reference clock (32 KHz) which,
through an FLL circuitry, can be used to generate the microcontroller system clock. The
internal reference clock can be calibrated (trimmed) with precision. To do so, open the
Communication Settings dialog box.
To open the Communication Settings dialog box, enter a CodeWarrior debugging session and
select “MCU Configuration” from the “SofTec-RS08” menu. The following dialog box will
appear.
The MC9RS08KA2 microcontroller’s ICSTRM register and the FTRIM bit in the ICSSC register
will be then programmed with a specific value which will result in the DCO output frequency
specified.
