I have two issues with the QEI module
1.  I only have the index pulse detected interrupt enabled (QEIIE bit 0) however the intterupts status (QEIINTSTAT) Shows multiple interrupts.
2. The counter will always reset on an index pulse.  I have not set the RESPI bit in the QEICON register
Is there an errata on this module that I have not found?

The first issue is not a big deal I can mask the interrupts that I am looking for.
any help or ideas would be appreciated.
