6.4. Viewing and Modifying Registers
All registers on the device can be viewed and modified when the device is in a halted state. The registers are
grouped together according to which peripheral or part of hardware they belong. As an example, this guide shows
how to open the ADC0 Debug Window and disable the ADC0 directly from the IDE.
1. Open the ADC0 Debug Window from the View Debug Windows SFR’s ADC0 menu option. The
2. In the debug window, change the value of ADC0CN from 0x82 to 0x02. This value turns off the ADC on the
3. To write this new value to the device, select Refresh from the Debug Menu or click the Refresh button in the
4. Click “Go” to resume running the device with the new ADC0CN value.
5. Turn the potentiometer on the daughter card and notice that it has no effect on the blinking rate of the LED.
6. Re-enable the ADC by writing 0x82 to the ADC0CN and clicking the Refresh button.
ADC0 Debug Window appears on the right-hand side of the IDE. In this window, the ADC0CN register is shown.
This register is used to enable and configure the on-chip ADC. When the firmware is running, the ADC0CN
register reads as 0x82 indicating that the ADC is running.
