This confirms also the usual ratio = 10 between Sp1 and Sp2 which is defined in
AVR498 Application Note.
To avoid a shorten last step, this phase monitors the last ramp-up step to guarantee it
is ended properly before running in closed loop.
The Running phase is a sensorless closed loop which block diagram is following :
