TM4C1237D5PM: Minimise power consumption on startup

Part Number: TM4C1237D5PM

Tool/software:

Hello

I would like to know the best way to minimise the power consumption of the TM4C1237D5PMI IC on startup.

I know about Hibernate and sleep modes.

However, I would like to know if there are any settings or method to minimise the power required when the chip first starts, or does it have to start in full power and only then can it switch back to one of the lower powered modes of operation.

    Hi,

      The MCU does not start in hibernate or sleep mode. After reset, it starts in run mode. In the main() function, you can enter the low power mode of your choice.
