D.12 Fast Quadrature Decode TPU3 Function (FQD)
FQD is a position-feedback function for motor control. It provides the RCPU with a 16-bit free-running
position counter by decoding the two signals from a slotted encoder. FQD incorporates a “speed switch”
that disables one of the channels at high speed, allowing faster signals to be decoded. Furthermore, every
counter update provides a time stamp that is useful for interpolating position and determining velocity at
low speed or in instances that implement low-resolution encoders. The ITC function handles the third
index channel provided by some encoders. See Freescale TPU Progamming Note Fast Quadrature Decode
TPU Function (FQD), (TPUPN02/D).
