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 ?
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?
