(4) Killer output pin is available for system identification by MICOM.
(Killer"On" → 0 V : Either color signal is not properly detected due to wrong system settig, or the color signal
field strength is too weak.
Killer"Off" → 5 V : Color signal is properly detected.)
When killer is on, according to the MICOM control sequence,the mode and VCO frequency will be switched
by means of the I2C bus.
(5) During SECAM, the color difference output pins are put into high impedance.
(6) AN5344(color-compensation IC)and other types of feature IC can be connected because color difference
input pins are available.
(7) It is possible for South American set application.

Note) For PAL M, crystal MEIDEN 3575 & C = 18 pF are used.
For PAL N, crystal MEIDEN 3012-M & C = 22 pF are used.
In order to extend downwards the β curve, a capacitor of 2 pF to 4 pF is added between Pin7 and GND.
