TPA3138D2: SD/FAULT pin and Mute time

Part Number: TPA3138D2

Hello

 

 Can you correct my understanding for following items?    

1. SD/FAULT pin ,
   Must be tied to PULL-UP register?  

  Register value( 4.7K-500K) can be defined based on MCU's drive performance.  Is it correct?

2. Mute time.   
    SD/Fault pin is changed from Low to High.   
    Mute lease time is tON( Typical 50ms ).   is it correct?

Best regards,
