I'm trying to determine if it is possible to use the internal clock on the s12p. How accurate is the internal clock on the s12p when trimmed at the factory using CPMUAPITR?
I guess one would have to know what the tolerance is on a typical oscillator. If an oscillator has a frequency of 4Mhz and a tolerance of 100ppm, does this mean 4Mhz+/- .01%? If so, the internal oscillator would have to be trimmed extremely well to be similar. If it is similar to s08 products, the accuracy is around +/-5%. Not good enough for my application (need .5%).
thanks in advance
