> you'll want to ensure that any floating MCU pins Stop right there. Floating CMOS inputs are generally not a good idea, even if they can be configured to shut off the digital receiver. Yes, in some cases, you really can shut off the power to the digital receiver, but in the general case, you're better off configuring a pullup or pulldown on the pin, to keep it out of the CMOS transition region.
