For the full step excitation, the phase pattern VPM[3:0] (See Table 12-1 and Table 12-2) needs to be put into

VPMF[3:0] of this VPMPattern register. Bit[7:4] of this register are ‘don’t care’.

For the half step excitation, two adjacent phase patterns (See Table 12-3) need to be put into the VPMPattern

into VPMH[3:0]. The current output at PM[3:0] is VPMF[3:0].
