The motor setpoint register is used to set the speed of the
motor in Quasi CLV mode. QCLV motor control is switched
off by making the setpoint equal 00100000. See Table 22
for setpoint/speed values. Note that these are measured
values. They were measured using the motor control
bread board. This bread board was hooked onto a ROM
65000 loader 12.66 application. The filter in the config
control (Cnf_filter) was switched off. A motor gain of 5 was
used. The register is byte addressable; R/W.
