Behaviors of internal signal A,B and output signal F, D when a rotating magnetic field is applied on AK8776

F signal (pulse) is correspond to the result of internal signal A and B. And D signal (direction) is given by looking up

the state of signal A and B.

*M.F.D. is Magnetic Flux Density.

Note) D signal is determined after one pulse sent out of F signal. The section which the output status is undefined

appears only in the starting up of this device.
