LABEL
DESCRIPTION
0
THERMAL
Thermal Shutdown = 0 indicates that the chip temperature has exceeded 160°C.
The bit will reset (=1) when the temperature falls below 130°C. When Thermal
Shutdown =0, the spindle logic will tristate both high and low side drivers,
protecting the output circuitry.
1
THERM_WARN
Thermal Shutdown Warning =0 indicates that the chip temperature is
approximately 25°C before the device goes in thermal shut down.
2
ROTOR_STUCK
0 = A sequential Spindle BEMF has not been detected
3
FAULT
1 = Rapid deceleration of the Spindle motor or High frequency on FCOM signal.
4
MASK_TIME
Mask Time toggled to "0" indicates that the Spindle BEMF is masked.
5
ERROR_LOCK
0 = Indicates error Spindle speed > 16msec/sample, either electrical or
mechanical.
6
ALIGN
0 indicate that the Spindle is in the Internal Start-Up Align Phase.
7
GO
0 indicate that the Spindle is in the Internal Start-Up Go Phase.
