NCO Frequency modualtion

Hi, I am trying to make a frequency sweeper with an NCO. Can anyone tell me how the modulation input into the NCO works. I want it sweep from 1MHZ to 48MHZ? Thank you in advance.

So i would generate these tuning words say using a counter and just input them straight into the phi_inc_i input?

Would the best way to do this using a counter with my required steps?

Cheers
