If SYNCP and SYNCA are generated from different clocks, be sure to keep the relative
timing of the rising edges of SYNCP and SYNCA (that is, which rising edge is earlier) after
releasing the reset.
The recommended condition (values) for the clock duty cycle need not be observed if the clock
duty cycle fulfills the digital interface timing.
