Masking Using FREEZE/RESUME Registers
As shown in Figure 33, the FREEZE/RESUME registers are us
to temporarily mask the XV outputs. The pixel locations to
begin the masking (FREEZE) and end the masking (RESUME)
create an area in which the vertical toggle positions are ignored
At the pixel location specified in the FREEZE register, the XV
outputs will be held static at their current dc state, high or low
The XV outputs are held until the pixel location specified by the
Rev. A | Page 25 of 96

.
.
RESUME register is reached, at which point the signals will
ontinue with any remaining toggle positions. Two sets of
FREEZE/RESUME registers are provided, allowing the vertical
utputs to be interrupted twice in the same line. The FREEZE
nd RESUME positions are programmed in the vertical pattern
roup registers, but are enabled separately using the VMASK
gisters. The VMASK registers are described in the Vertical
Sequences (VSEQ) section.

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 VPAT GROUP, USING FREEZE1/RESUME1 AND FREEZE2/RESUME2 REGISTERS.
