Masking Using Freeze/Resume Registers
As shown in Figure 42 and Figure 43, the FREEZE/RESUME
registers are used to temporarily mask the XV outputs. The
pixel locations to start (FREEZE) and end (RESUME) the
masking create an area in which the vertical toggle positions are
ignored. At the pixel location specified in the FREEZE register,
the XV outputs are held static at their current dc state, high or

NOTES
1. ALL TOGGLE POSITIONS WITHIN THE FREEZE-RESUME MASKING AREA ARE IGNORED. H-COUNTER CONTINUES TO COUNT DURING MASKING.
2. TWO SEPARATE MASKING AREAS ARE AVAILABLE FOR EACH GROUP A, USING FREEZE1/RESUME1 AND FREEZE2/RESUME2 REGISTERS.

low. The XV outputs are held until the pixel location specified
by the RESUME register, at which point the signals continue
with any remaining toggle positions.
Two sets of FREEZE/RESUME registers are provided, allowing
the vertical outputs to be interrupted twice in the same line. The
FREEZE and RESUME positions are enabled using the VMASK
register.
