HORIZONTAL AND VERTICAL GATING SIGNALS
Horizontal Drive and Vertical Drive outputs can be utilized
as general purpose Gating Signals. Horizontal and Vertical
Gating Signals are available for use when Composite Sync
and Blank signals are selected and the value of Bit 2 of the
Status Register is 0. The Vertical Gating signal will change
in the same manner as that specified for the Vertical Blank.

CURSOR POSITION AND VERTICAL INTERRUPT
The Cursor Position and Vertical Interrupt signal are avail-
able when Composite Sync and Blank signals are selected
and Bit 2 of the Status Register is set to the value of 1. The
Cursor Position generates a single pulse of n clocks wide
during every line that the cursor is specified. The signals
are generated by logically ORing (ANDing) the active LOW
(HIGH) signals specified by the registers used for generat-
ing Horizontal and Vertical Gating signals. The Vertical
Interrupt signal generates a pulse during the vertical inter-
val specified. The Vertical Interrupt signal will change in the
same manner as that specified for the Vertical Blanking sig-
nal.
