The zero signal is only output if released by the
input pins (for instance with PZERO = 5 V, NZERO =
VREF).

Figure 12: Incremental output signals for various zero signal lengths.
Example gives a resolution of 64 (SELRES = 0x0A), a zero signal position of 45° (ZPOS = 0x04,
CFGAB = 0x00) and no inversion of the direction of rotation (ROT = 0x00, COS leads SIN).
