MOTOR CONTROLLER (Cont’d)

Note

If only one encoder output is available, it may be

input either on MCIA or MCIB and an encoder

clock signal will still be generated (in this case the

frequency will be 50% less than with two inputs.

The state of EDIR bit will depend on signals

present on MCIA and MCIB pins, the result will be

given by the sampling of MCIA with MCIB falling

edges.
