0xFFFF FFFF
27.6.2.12
QEI Velocity Compare register
This register contains a velocity compare value. This value is compared against the
captured velocity in the velocity capture register. If the capture velocity is less than the
value in this compare register, a velocity compare interrupt (VELC_Int) will be asserted, if
enabled.

27.6.2.13 QEI Digital filter on phase A input register
This register contains the sampling count for the digital filter. A sampling count of zero
bypasses the filter.
