Others: Preset
(1) Connect Pin61 to GND via a 1uF capacitor.
(2) Set Color System to 4(443PAL).
(3) Adjust Pin7 voltage so that the Pin34 output frequency is
4.433619MHz that is V4APCCEN.
(4) Measure the Pin34 output frequency when Pin7 voltage is
V4APCCEN+200mV / V4APCCENT, that is F4APC+ / F4APC-.
(5) Calculate; "β443"=(F4APC+-F4APC-)/200
(6) Set Color System to 2 (358NTSC).
(7) Adjust Pin7 voltage so that the Pin34 output frequency is
3.579545MHz that is V3APCCEN.
(8) Measure the Pin34 output frequency when Pin7 voltage is
V3APCCEN+200mV / V3APCCEN, that is F3APC+ / F3APC-.
