Phase Offset Bits:
These seven bits refer to the 2’s complement phase word to
control the DPLL output phase offset. The offset varies in steps of 15 ns if the
reference is 8 kHz or 2.048 MHz. The offset varies in steps of 20 ns if the reference
is 1.544 MHz.
Reserved.
Skew Control Bits:
These three bits control the delay of the DPLL outputs from 0
to 7 steps in interval of maximum unit delay of 3.5 ns.

Secondary Loss Detection Bit (Read-only bit):
This bit is the same as the output
from the DPLL Reference Monitor FAIL_SEC.
Primary Loss Detection Bit (Read-only bit):
This bit is the same as the output from
the DPLL Reference Monitor FAIL_PRI.
DPLL Clock Monitor Bit:
When high, the primary output C32/64o is 65.536 MHz clock.
When low, the primary output C32/64o is 32.768 MHz clock. This is the only writable bit
in this register.
Limit (Read-only bit):
Indicates that DPLL Phase Slope limiter limits input phase.
