Hello

 

Whether BITSLICE_CONTROL.EN_VTC signal must be pulled Low during modifying PQTR/NQTR values?

Doubled checked and you do not need to make the EN_VTC of the BSC low when changing the  PQTR/NQTR. It would be a good step after updating the PQTR/NQTR delay to read it back to make sure they got updated as programmed. 

Thanks,

Sandy

When you are changing the delays of the BITSLICE you are meant to pull the EN_VTC of the BITSLICE Low, so it makes sense to pull the EN_VTC of the BSC low when you make a PQTR/NQTR change so that two things are not trying to update at the same time. 

I'll try to verify that can get back to you.

Thanks,

Sandy
