RETDIR
Retract Direction.
“0” VCM- high, VCM+ low. “1” VCM- low, VCM+ high.
6
RETRACT
“1” Retracts the Voice Coil arm.
7
RETBRK
“1” Brakes the VCM for the first 20mS of the retract time then it reverses
the direction of the retract opposite to the RETDIR bit setting for other
20mS, then it finish the normal retract. This total 40mS are
subtructed from the programmed Retract time.
