If the index event occurs during forward movement, then the position counter is reset to 0 on the next eQEP clock. If the index event occurs during the reverse movement, then the position counter is reset to the value in the QPOSMAX register on the next eQEP clock. Note that this is done only on the first occurrence and subsequently the position-counter value is not reset on an index event; rather, the position-counter value is reset based on the maximum position as described in Section 23.5.1.2.
The first index marker fields (QEPSTS[FIDF] and QEPSTS[FIMF]) are not applicable in this mode.
