Y1 output
Outputs the Y signal that
routed the fsc TRAP
(TRAP can be turned on
or off with bus.) and the Y
delay line circuit.

SECAM
control
The input/output pin that is
used to control the
SECAM demodulation IC.
When current stronger
than 250
A flows from
this pin, that is recognized
as SECAM.

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
.
