This is a CubeSat Kit question ... regardless, the processor frequency is specified in the datasheet, and is currently 7.3728MHz and 32.768kHz for PPM A1 / A2 / A3.

N.B. The '2618 used in PPM A3 is capable of running at up to 16MHz. For the interests of backwards compatibility, however, we are currently keeping PPM A3's HFXTAL at 7.3728MHz.

Hey,
I am using REV C development board right now for my application with the MSP430F2618. But the final code, application is going to be deployed on REV D ( We have procured 2 Flight modules REV D). I wanted to know wat is the operational frequency of REV D board and wat changes or effect it will have on my code. I think the SMCLK frequency still remains the same even if the crystal frequency changes.

Please give us details if any changes in the code regarding the frequency will have to be made or SMCLK will it change or not.
We need details abt REV D frequency since its not mentioned in the document.

Thanks a lot,
Ankush
