DRV8243-Q1: Questions of DRV8243-Q1

Dear Team,

we have some questions as below,

1. Can the FAULT# pin of the Motor driver be shared by four?
2. FAULT# Viewing pictures can be locked, how can I unlock it?
3. If my FAULT# signal needs to be isolated by an optocoupler for digital signals, which side should the pull high be on?

Many Thanks,

Jimmy
