The HALLD function decodes the sensor signals from a brushless motor, along with a
direction input from the CPU, into a state number. The function supports two- or three-
sensor decoding. The decoded state number is written into a COMM channel, which
outputs the required commutation drive signals. In addition to brushless motor appli-
cations, the function can have more general applications, such as decoding “option”
switches. See Motorola TPU Progamming Note
(HALLD), (TPUPN10/D).
