The maximum clock frequency that can be used with the internal oscillator is 12 MHz. However, it's recommended to use a crystal oscillator for frequencies above 4 MHz for better accuracy and stability.
The pin multiplexing can be configured using the PINSELx registers. Each peripheral function has a corresponding PINSELx register that needs to be set to enable the desired function on a specific pin. Refer to the datasheet for the specific register and bit settings for each peripheral.
The minimum voltage required for the ADC to operate correctly is 2.4 V. The ADC may not operate correctly or may produce incorrect results if the voltage is below this threshold.
To implement a watchdog timer reset, you need to enable the watchdog timer by setting the WDTENA bit in the WDTMOD register. Then, you need to periodically reset the watchdog timer by writing a specific value to the WDTFEED register. If the watchdog timer is not reset within the timeout period, it will generate a reset signal.
The maximum current that can be sourced or sunk by the GPIO pins is 4 mA. Exceeding this current limit may damage the device or affect its reliability.
