TRAP
(TRAP can be turned on
or off with bus.) and the Y
delay line circuit.
68 NC
None connect PIN.
These pins connect to
GND.
69 control
The input/output pin that is
used to control the
SECAM demodulation IC.
When current stronger
than 250
μ
A flows from
this pin, that is recognized
as SECAM.

When SECAM
0.75 V
70 SCP output
Outputs SCP (sand castle
pulse).
The output signal consists
of clamp pulse, horizontal
blanking pulse, and
vertical blanking.
The minimum load
resistance is 3 k
.
