I have a shift register with an asynchronous reset to convert serial to parallel data. All that I do is to shift data through it and decode the data to get the address to be read/written to in an efuse.

I have a simple question. Consider, I disconnect the power supply to the flops. THis would make the output of the flops to float. Now, my question is, When I power the design back on, is it mandatory for me to reset the flip-flops or if I shift valid data through it, it should work fine? The efuse does not have to be reset as it will always hold its value.

THanks

Arun
