I believe that this does the trick: USBCON |= (1 << USBE); PLLCSR |= (1 << PLLE); // Resume the USB Clock (PPL) USBCON &= ~(1 << FRZCLK); // Resume the USB Clock

Just in case anyone else has this question, I found that the LowPower library that I am using doesn't turn off the USB clock. When I do that using the code below before putting the MCU in idle mode, the consumption...

Thanks for this reply, Paul! I was beginning to think that the datasheet is indeed misleading. I am testing idle current with most peripherals (USB, ADC, SPI, etc. turned off), and still getting 4.5 mA, which is in the...
