FUNCTION
A pulse to clamp the optical black signal. This pulse
is continuous at horizontal cycle when CPMD (pin
25) and CPBL (pin 36) are Low.
and CPBL is Low, output stays Low during the ab-
sence of effective pixels within the Vertical blank-
ing, otherwise is continuous at horizontal cycle.

The pulse is used in color separator. The signal
switches H and L at every line. It resets at the
14th line when in NTSC, and at the 9th line when
in PAL mode.
