Timing
Power ON / OFF (Tape recorder not present)
Note: *DLC is data that controls the tuner IC. In particular, it is charge pump control data that forcibly controls the
charge pump output. A value of 0 specifies normal operation and a value of 1 forcibly sets the output low.
It is used as follows. When a deadlock due to the VCO oscillator stopping when the VCO control voltage
(Vtune) is 0 V occurs, it allows escaping from the deadlock state by setting the charge pump output low and
Vtune to VCC. (Deadlock clear circuit)
