Audio reference voltage supply. 2nd low pass filter. Audio 5V power supply. Focus tracking actuator, Sled/Spindle MD deck up/down motor driver. Servo control / Mechanism control / Multiple purposes interface. Mechanism up/down position offset servo initial data memory. Resets u-com. DAC. Memorises data from text decoder through u-com. Bus driver. "ON" when IC13's APC goes on. 0 bit mute goes on when "H" level signal is putout from LZ port of IC6. 0 bit mute goes on when "H" level signal is putout from RZ port of IC6. Mute goes on when "L" level signal output from A. MUTE port of IC7. Mute goes on when "L" level signal is output from A. MUTE Port of IC7. Transistor with regulator inside the IC12. SW5V turns on when "L" level signal is output from P.ON port of IC7. Resets u-com by "H" level reset control signal from the head unit. Clock goes off when "H" level signal is output from XOFF port of IC7. Works during the ACC and power on. Audio mute output
