27. Reset circuit; Pin 68: RES
When power is first applied, this pin should be briefly set low and then set high. This will set the muting to –
∞
dB
and stop the disc motor.
28. Sound output function for set adjustment during manufacturing; Pin 30: DEMO
The DEMO pin can be used when the LC78625E is used in combination with an LA9210M or LA9211M.
By setting this pin high, muting can be set to 0 dB, the disc motor can be set to CLV, and a focus start operation can
be performed, even without issuing any commands from the control microprocessor. Also, since the LASER pin
becomes active, if the mechanism and servo systems are complete, an EFM signal can be acquired with only this
equipment, and an audio signal can be produced without the presence of a microprocessor. However, since the digital
attenuation is set to 100H, this technique is not appropriate for evaluating audio quality.
