NOTES
1. EXTERNAL HD FALLING EDGE IS LATCHED BY CLI RISING EDGE, AND THEN LATCHED AGAIN BY SHD INTERNAL FALLING EDGE.
2. INTERNAL H-COUNTER IS ALWAYS RESET 35.5 CLOCK CYCLES AFTER THE INTERNAL HD FALLING EDGE.
3. DEPENDING ON THE VALUE OF SHDLOC, H-COUNTER RESET CAN OCCUR 36 OR 37 CLI CLOCK EDGES AFTER THE EXTERNAL HD FALLING EDGE.
4. SHDLOC = 0 IS SHOWN IN ABOVE EXAMPLE. IN THIS CASE, THE H-COUNTER RESET OCCURS 36 CLI RISING EDGES AFTER HD FALLING EDGE.
5. HD FALLING EDGE SHOULD OCCUR COINCIDENT WITH VD FALLING EDGE (WITHIN SAME CLI CYCLE) OR AFTER VD FALLING EDGE. HD FALLING
EDGE SHOULD NOT OCCUR WITHIN FIVE CLI CYCLES PRIOR TO THE VD FALLING EDGE.

Figure 90. Example of Slave Mode Register Setting to Obtain Desired Toggle Positions
Vertical Toggle Position Placement Near Counter Reset
An additional consideration during the reset of the internal
counters is the vertical toggle position placement. Prior to the
internal counters being reset, there is a region of 36 pixels
during which no toggle positions should be programmed.
As shown in Figure 91, for master mode the last 36 pixels before
the HD falling edge must not be used for toggle position placement
of the V, VSG, SUBCK, HBLK, PBLK, or CLPOB pulses.
Figure 92 shows the same example for slave mode. The same
restriction applies: the last 36 pixels before the counters are
reset cannot be used. However, in slave mode, the counter reset
is delayed with respect to VD/HD placement, so the inhibited
area is different than it is in master mode.
It is recommended that Pixel Location 0 not be used for any of
the toggle positions for the VSG and SUBCK pulses.
