10V power supply with a maximum output current of 300mA for a illumination.
AM and ANT output are turned ON when this pin is 5V.
AM and FM output are switched when this pin is 5V.
Only VDD output during the 0V standby state; ILL,COM and AMPoutputs
are turuned ON when this pin is 5V.
5.6V Power supply with amaximum output current of 100mA for a micro-
controiler. Output is always available if BACKUP power supply is connected.
