Notes:
d) Digital inputs left within or near the transition region substantially increase power supply
current by drawing power from the internal 5V regulator. Make sure that digital inputs
become driven near to 0V and up to the V

I/O voltage. There are no on-chip pull-up or pull-
down resistors on inputs.
