= External input
Selects the internal mode switching method.
Selects the V cycle when sync cannot be obtained if automatic switching
is selected by SYSTEM1.
Selects the V cycle.
Inputs the input signal broadcast system.
Selects the VCO frequency
Selects which of the crystals connected to the various pins to use.
Inputs whether the crystal connected to Pin 2 is 3.58 MHz or 4.43 MHz.
(When connecting a 4.43 MHz crystal, be sure to connect it to Pin 2.)
Forcibly switches the DET SW input to external input (R-Y IN, B-Y IN).
Allows the following delay times to be added to the Y signal.
