Register 7: QEI Velocity Counter (QEICOUNT), offset 0x018
This register contains the running count of velocity pulses for the current time period. Since this is
a running total, the time period to which it applies cannot be known with precision (that is, a read of
this register does not necessarily correspond to the time returned by the QEITIME register since
there is a small window of time between the two reads, during which time either value may have
changed). The QEISPEED register should be used to determine the actual encoder velocity; this
register is provided for information purposes only. This counter does not increment when VelEn in
QEICTL is 0.
