If i not plan to use the BUSY and FRSTDATA signal lines, how should I leave them? Floating, grounded?
And i am not planning to use them, due to the fact that i am using the adc very "slowly" so i am not reliant to them.
As both are digital outputs it is acceptable to leave them floating/unconnected.
Please note that when CS\ is high that FRSTDATA will be tri-state.
