I wish to use the stopwatch while experimenting with Olimex PIX_MICRO-WEB embedded ethernet PIC18F67J60 which has a 25MHz external xtal and a OSCTUNE value of 0x40 which produces a clock freq of 41.667MHz. I am not sure which value which value to enter in the Processor Frequency input box. As it is titled Processor Frequency and not Clock Freq I am leaning towards 41.667/4 MHz. ~ 10.41675Mhz. However, I am not 100% sure if the simulator takes into account the OSCTUNE value or if it is actually asking for the clock freq. (still) using MPLAB IDE 8.33 (X seemed a bit overwhelming) debugging with MPLAB SIM and pickit2.
