are not loaded. Sleep mode defined by 000 as spindle code and VCM disable.
Switching levels with respect to SDRVU, SDRVV and SDRVW.
For the description of the Power-on reset see Fig.6.
On spindle motor drivers:
a) Zero duty factor guarantees zero current output.
b) 5% duty factor guarantees current output.
c) Maximum current will be activated at 100% duty factor.
