I'm setting up the clock configuration for a new design, and would like to understand the Frequency Correction Loop options. I'd like to know if it's possible to use the SYSOSC at 32MHz with the frequency correction loop enabled and an internal ROSC oscillator. Figures are given for this configuration in section 7.9.1 of the datasheet for this part. However, when I go to set it up in the SYSCFG tool I get an error saying that I need to enable the external ROSC setting:
Should I expect to be able to use an internal resistor? Is SYSCFG incorrect? Or is it my understanding that's wrong?
