I am trying to put the USB PHY to low power suspend mode (18.104.22.168 Entering Low Power Suspend Mode) in USB device mode.
If I follow the above procedure and step through my code with a debugger the USB PHY TX parts will
be automatically cleared (normal operation) after setting them to 1 by software (no USB cable is connected to my RT1020 EVK).
Maybe it is due to the battery charger bit not being set to 1. Where can I find information about the integrated battery charger and its registers? I can't find a chapter about the battery charger and its registers in the reference manual.
