MultiSynth2 Initial Phase Offset.
MultiSynth2_PHOFF[14:0] is a 2s complement number. The initial
phase offset is MultiSynth2_PHOFF[14:0] x Tvco/128 where Tvco is
the period of the VCO.
MultiSynth2 Phase Step Size.
The phase step size is MultiSynth2_PHSTEP[13:0] x Tvco/128 where
Tvco is the period of the VCO. Either the phase inc/dec pins (if avail-
able) or register 74[1:0] will control the stepping of phase. A phase
increment will delay the clock edge.
