MAX32660 consumption spike on startup


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?
