Download Step 6: Configure Oscillator The next step is to start programming; however, before we get to the application code we must program the system code. The system code are the low level functions such as configuring the oscillator and basic delay functions.
Determining Settings Before we can program the settings, we must choose what speed we would like to run at. If you are using the internal oscillator then use the settings relating to INTIO1 On the next page or two you will find a schematic drawing of the oscillator similar to the one shown.
It is helpful to trace the signal on this drawing to ensure the correct speed is being selected. The next step is to program these settings to the MCU. This is done by setting registers. IDLEN -- used to control the action of the sleep command. Can be left as default. IRCF -- Oscillator selection. Remove the comments in that function. To set the bits of a register type in all caps the register name, followed by the lowercase word bits and then a period and the bit name.
To set the bits follow that with an equal sign. Lastly end the line with a semi-colon. See below for an example of a finished ConfigureOscillator function.
