ADE7880 ZX indication

How can I get HW indication for Zero Cross of each phase in the ADE7880? The only way I found is by interrupt line and finding what phase caused it by the status bits. The problem is that this is time consuming and the interrupt is for both rising and falling of the zero cross of each phase unlike the HW ZX line there is in the ADE7953 chip where there is ZX line that shows exactlly when the ZX is rising or falling and can be connected to external HW for our use?
