About EMIF recalibration and transceiver recalibration

Hi Sir,

Yes, both IP has different reset scheme, one using reset input pin while one using the register method.

I think the reason is EMIF IP does not need/support reconfiguration. So, using the single input to reset/recalibrate the IP is sufficient.

However, for XVCR, it will need reconfiguration, as what I know, during reconfiguration, the user not only need to reset the IP but also need to write into other registers to meet the requirement, so it will need register method to do all the work like reset and reconfiguration.

By the way, this is not a problem, all of these are based on the IP usage model needs.

Hope this helps.
