MTIE Reset
When this bit is low, the MTIE circuit applies a phase offset between the reference input
clock and the DPLL output clock and the phase offset value is maintained. When this bit
is high, MTIE circuit is in its reset state and the phase offset value is reset to zero,
causing alignment of the DPLL output clocks to nearest edge of the selected input
reference.
6 - 5
PRS1 - 0
