For the UCD9244, what should i do with any unused input pins? Specifically, I'm wondering about unused VID pins, unused inputs to the 12-bit ADC (CS, temp/aux, etc) and unused inputs to power peripherals (EAp, EAn, FLT, etc). Does the UCD9244 insert a pullup or pulldown on these inputs if programmed to be not used, or should I short these to GND?
