state output

1 The power-off port state is set, the tuner is turned off, and serial communication is broken. But if the

initial setting diode CLKDSP = 1 (shorted with diode), the operations of breaking serial communication

and turning off the LCD power output are not implemented.

2 The LCD power pin is also turned ON by this timing.

3 Tuner is turned on, sound source mode is started, serial communication is started and call back for the

last preset memory is started (If the sound source is the tuner, mute on remains.)

4 Call for last preset memory is completed.

Note Timing for detecting key and panel changes (time to eliminate chattering is not included).
