(pins 28, 29) switch. When the pin
voltage is 2.8 V or more, the mode
changes to the 3.58 MHz mode;
when 2.2 V or less, to the 4.43
MHz mode.
Pin for controlling switch of NTSC
and PAL modes of decoder and
matrix. One of the following three
combinations of decoder and
matrix modes can be selected
depending on the value of the pin
42 voltage V42:
1. When V42 = 0 V
decoder = PAL
matrix
= PAL
2. When V42 = 2.5 V
decoder = NTSC
matrix
= NTSC
3. When V42 = 5 V
decoder = NTSC
