We have a project with FEI mode and internal 32 kHz oscillator. It gives us output of 21.97 MHz. We would like to have a 24 MHz clock, so we have to trim the frequency of oscillator. There is a register SCTRIM, which does it, but its value is different in every MCU(as oscillator is callibrated in factory). Is there somewhere a more detail information, what are the weights of bits in SCTRIM register? We cannot use external oscillator because of price reasons. The value of SCTRIM is proportional to value of SCTRIM or value of oscillator frequency?
And what about setting DMX32 bit to 1 in FEI with factory trim value? Will it damage MCU?
