AD9910 autoclear phase accumulator

Hello everyone,

I'd like to know which is the function of the Autoclear phase accumulator (bit 13) in the CFR1 of AD9910.

If I set the bit Autoclear phase accumulator = 1 anytime that an I/O_UPDATE occurs the phase of the sweep is resets? So a new sweep starts with phase zero?

Otherwise, if I set the bit Autoclear phase accumulator = 0 the phase accumulator works normally. So a new sweep starts with the same phase of the previous sweep?

 

Best regards

Gio.
