#85940 - Leave them unconnected Responding to: ???'s previous message |
Payam said:
Is it safe (from the noise immunity point of view) to leave them unconnected? Leave them as they are: Programmed as inputs after power on reset and unconnected. Noise immunity is not the issue. If you have so much noise that an unconnected and internally pulled-up input would be pulled-down, then you have a different problem... Kai |
