Hold Area Using FREEZE/RESUME Registers

The FREEZE/RESUME registers can also be used to create a

hold area in which the V-outputs are temporarily held and later

continued, starting at the point where they were held. As shown

in Figure 46, this is different than the VMASK_EN register because

the V-outputs continue from where they stopped rather than

continuing from where they would have been. The hold area

temporarily stops the pixel counter for the V-outputs, while the

V-masking allows the counter to continue in the masking area.

NOTES

1. WHEN HOLD = 1 FOR ANY V-SEQUENCE GROUP, THE FREEZE AND RESUME REGISTERS ARE USED TO SPECIFY THE HOLD AREA.

2. ABOVE EXAMPLE: XV1 TO XV10 ARE ASSIGNED TO GROUP A. HOLD BIT FOR GROUP A = 1.

3. H-COUNTER FOR GROUP A (XV1 TO XV10) STOPS DURING HOLD AREA.
