The maximum clock frequency that can be used with the internal oscillator is 20 MHz.
To configure the watchdog timer to reset the microcontroller, set the WDT_C1[WDT] bit to 1 and the WDT_C1[WDTS] bit to 0. Then, set the WDT_C2[WDTOF] bit to 1 to enable the watchdog timer.
The VLLS mode is a low-power mode that reduces power consumption to a minimum by shutting down the CPU, peripherals, and most of the internal logic. It is used to minimize power consumption when the microcontroller is not in use.
To use the ADC, configure the ADC_SC1 register to select the channel and conversion mode, then start the conversion by setting the ADC_SC2[ADTRG] bit to 1. The converted digital value can be read from the ADC_R1 and ADC_R0 registers.
The COP watchdog timer is a safety feature that resets the microcontroller if it fails to periodically reset the COP timer. This ensures that the microcontroller is operating properly and prevents it from getting stuck in an infinite loop.
