Figure 2:
Spindle State Diagram.
NOTE: In the spindle state diagram, in transitioning from Start mode to Brake, the CPR register is shown
as being one possible path. The CPR register can be used to command a brake, which then causes the
outputs to brake. This is called CPR Brake mode. However, a true brake state does not really occur.
Specifically, current limit is still active.
NOTE: START and SP_EN bits and CPR is rewritten to get out of Spindle Z state. SP_EN must be
pulsed.
NOTE: All spindle state transitions require an SP_CLK edge.

Figure 3:
VCM section state diagram.
NOTE: VC_EN must be rewritten to get out of VCM Grounded state.
NOTE: At start, the spindle and VCM can now be simultaneously enabled. This is a VERY HIGH
POWER DISSIPATION mode. If this is done, be sure to use the SAT_SK bit and duty cycle the
VCM to keep chip power dissipation at a reasonable level.
