Note: The available control bits in the DFLTCON Register may vary depending on the dsPIC30F device that is used. Refer to Register 16-2 and Register 16-3 for

details.

Note: On many devices, the QEI pins are multiplexed with analog input pins. You will need to ensure that the QEI pins are configured as digital pins using the

ADPCFG control register.
