The states shown above in boxes are set directly when RES is low.
Audio Output for Calibration (pin 27: DEMO)
Setting this pin high sets muting to 0 dB and the disc motor to constant linear velocity, even when the microprocessor
issues no command, and activates focusing. Because this also makes the LASER pin active, EFM signals and audio
output can be obtained without the microprocessor as long as the mechanism and servo are hooked up correctly.
Other Pins (pin 1: TEST1, pin 9: TEST2, pin 23: TEST4, pin 61: TEST5, pin 37: TEST6 and pin 32: TEST7)
These are test pins for the internal circuitry of the LC78681E. TEST1 through TEST5 have internal pull-down resistors.
The test inputs can be left open during normal operation.
