The EQEP peripheral includes a position-compare unit that is used to generate the position-compare sync signal on compare match between the position counter register (EQEP_QPOSCNT) and the position-compare register (EQEP_QPOSCMP). This sync signal can be output using an index pin or strobe pin of the EQEP peripheral.
Setting the SOEN bit in the EQEP decoder and control register (EQEP_QDEC_QEP_CTL) enables the position-compare sync output and the SPSEL bit in EQEP_QDEC_QEP_CTL selects either an EQEP index pin or an EQEP strobe pin.
