ade 7880 beginner's design

Hi,

 

I am trying to design a simplest energy meter using ade 7880 with SPI communication.

I am using ss,miso,mosi,sclk pins of ade7880 for SPI communication.

 

I have following doubt:

 

What all pins (from the below mentioned) in ade 7880 are not required(compulsorily) for control through programming or not required to be controlled by a micro-controller ?

irq0,irq1,reset,cf1,cf2,cf3.

What if i leave the above pins disconnected.

What if i am not handling any interrupt issues?

What if i am not using software reset?

Right now i just want to read/write registers through SPI (like an eeprom say). and just need to take the energy readings from the 7880 registers and store it in a memory.

 

what should be my minimum requirement to begin with ade 7880?

 

Please help me if it is feasible or not?

 

Thanks!

anur
