MAX32660 consumption spike on startup

Hi!

I'm using the MAX32660 in a low power application. When the µC is initialized and running (clock at 1.5 MHz) consumption is low enough (600µA) but I’m encountering an issue where the microcontroller shows a consumption spike of 6.5mA during startup.

Following the user manual's guidelines, I set the OVR register to 0x00, resulting in consumption decreasing to 1.6mA. Unfortunately, this is still too much.

Is it possible to reduce power consumptions even further during the startup?

Thanks
