DESCRIPTION
41 digital power supply
42 enable input; enables the serial port, i.e. allows DATA to be shifted in (active LOW)
43 under-voltage detector output flag (active LOW)
44 external capacitor for the RESETOUT duration
45 negative output of the VCM amplifier
46 delay control input for brake after park
47 test purpose 2 (should be left open-circuit)
48 reference oscillator input for motor speed control
49 ground 4 for the actuator driver
50 digital ground
51 inverting input of the VCM sense amplifier
52 non-inverting input of the VCM sense amplifier
53 output of the VCM sense amplifier
54 external voltage reference for the under-voltage detector
55 ground 2 for the spindle motor drivers
56 test purpose 3 (should be left open-circuit)
57 reset input; forces all bits of the SERIALIN register to 0 (active HIGH)
58 tachometer output (one pulse per mechanical revolution)
59 external capacitor for the charge pump output
60 motor driver output 1
61 external capacitor for the charge pump output
62 external capacitor for the charge pump output
63 external capacitor for the charge pump output
64 power supply for the spindle motor drivers
