STATE
DESCRIPTION
INIT
1
initializes the three bits commutation shift register in state 1 (see Table 13)
COMMCLK
0
commutation clock in stepper mode (one commutation every LOW-to-HIGH transition)
SPINMODE
0
stepper/BEMF detection mode selection. SPINMODE = 1 means stepper motor mode
in hard-switching configuration
SDISABLE
1
logic 1 sets the pre-drivers outputs LOW so that the spindle motor coils are in the
high-impedance state
SBRAKE
0
logic 1 sets the lower pre-driver outputs HIGH and the upper pre-driver outputs LOW
so that the spindle motor coils are shorted to ground
DATA BIT
RESET
STATE
DESCRIPTION
HARD_SW
0
logic 1 disables the soft switching circuitry, which means PWM is applied on the lower
FETs only.This mode is also forced in stepper motor mode.
LHOLD
0
logic 1 turns on the hold current supplied by VDDD through the latch. It is ignored if
LACTIVE = 1
LACTIVE
0
logic 1 turns on the activate current supplied by VDD through the latch
SLEEP
0
logic 1 disables spindle, VCM and latch driver outputs. The whole analog circuitry is
turned off except the reference bandgap and the voltage monitors. The uncommitted
operational amplifier is also cut off.
DATA BIT
RESET
STATE
DESCRIPTION
VGAINSEL
1
logic 1 turns on the switch between VCMIN1 and VCMIN2, resulting in a higher gain for the
transconductance of the VCM closed loop
VCM_CTRL_1
1
see Table 5
VCM_CTRL_0
1
see Table 5
