More than slow_line_nb lines with a phase

error less than the slow_tol will set the

slow status bit, and the pll will work with

the slow time constant.

One or more lines with a phase error more

than slow_tol will reset the slow status bit,

and the pll will work with the fast time

constant.

LSB of slow tol is approx. 200ps.
