66 NC
None connect PIN.
These pins connect to
GND.
67 Y₁ output
Outputs the Y signal that
routed the f_sc TRAP
(TRAP can be turned on
or off with bus.) and the Y
delay line circuit.

control
SECAM demodulation IC.
When current stronger
than 250 µA flows from
this pin, that is recognized
69
as SECAM.

SCP output
of clamp pulse, horizontal
blanking pulse, and
vertical blanking.
The minimum load
resistance is 3 kΩ.
