1 = finds the exact phase that is targeted (optimal setting).

Retry

R/W

0x0

0 = stop the search if the correct value is not found,

1 = retry the search if the correct value is not found.

CONTRST

R/W

Guard[4:0]

[4:0]

R/W

0x01011

Sets a guard band from the beginning and end of the Mu delay line, which

the Mu controller does not enter into unless it does not find a valid phase

outside the guard band (optimal value is Decimal 11 or 0x0B).
