The maximum clock frequency that can be used with the internal oscillator is 20 MHz, but it's recommended to use a crystal oscillator for frequencies above 8 MHz for better accuracy and stability.
To configure the watchdog timer, set the WDTCLK register to select the clock source, set the WDTCNT register to set the timeout period, and enable the watchdog timer by setting the WDTEN bit in the WDTCTL register. Make sure to periodically refresh the watchdog timer by writing to the WDTS register to prevent a reset.
No, the ADC can only measure voltages between 0V and VDD. If you need to measure voltages above VDD, you'll need to use an external voltage divider or attenuation circuit to bring the voltage within the ADC's input range.
To implement a low-power mode, use the STOP or WAIT instructions to put the MCU into a low-power state. You can also use the Bit Manipulation (BM) instruction to set the LPM bit in the SPMSC1 register to reduce power consumption. Additionally, disable any unused peripherals and set the clock frequency to the lowest possible value.
Yes, the internal flash memory can be used to store data that needs to be retained during power-down. However, make sure to follow the guidelines for flash programming and erase cycles to ensure data integrity and prevent wear-out.
