digital power supply
enable input; enables the serial port, i.e. allows DATA to be shifted in (active LOW)
under-voltage detector output flag (active LOW)
external capacitor for the RESETOUT duration
negative output of the VCM amplifier
delay control input for brake after park
test purpose 2 (should be left open-circuit)
reference oscillator input for motor speed control
ground 4 for the actuator driver
digital ground
inverting input of the VCM sense amplifier
non-inverting input of the VCM sense amplifier
output of the VCM sense amplifier
external voltage reference for the under-voltage detector
ground 2 for the spindle motor drivers
test purpose 3 (should be left open-circuit)
reset input; forces all bits of the SERIALIN register to 0 (active HIGH)
tachometer output (one pulse per mechanical revolution)
external capacitor for the charge pump output
motor driver output 1
external capacitor for the charge pump output
external capacitor for the charge pump output
external capacitor for the charge pump output
power supply for the spindle motor drivers
