Pixel 2 and Pixel 9 within a single HD line. However, in
multiplier mode the toggle positions are multiplied by
VLEN = 4; therefore, the first toggle occurs at pixel count = 8,
Rev. 0 | Page 36 of 88
and the second toggle occurs at pixel count = 36. Sweep mode is
also enabled to allow the toggle positions to cross the HD line
boundaries.
The MULTI function only applies to signals assigned to Group A.
It cannot be used at the same time as the TWOGROUP function or
if any signals are assigned to Group B.

High enables multiplier mode
Starting polarity of XV1 to XV13 signals in each VPAT group
Toggle positions for XV1 to XV13 signals in each VPAT group
Used as multiplier factor for toggle position counter

START POLARITY (ABOVE: STARTPOL = 0).
2
FIRST AND SECOND TOGGLE POSITIONS (ABOVE: XVTOG1 = 2, XVTOG2 = 9).
3
LENGTH OF VPAT COUNTER (ABOVE: VPATLEN = 4); THIS IS THE MINIMUM RESOLUTION FOR TOGGLE POSITION CHANGES.
4
TOGGLE POSITIONS OCCUR AT LOCATION EQUAL TO (XVTOG × VPATLEN).
5
IF SWEEP REGION IS ENABLED, THE V-PULSES MAY ALSO CROSS THE HD BOUNDRIES, AS SHOWN ABOVE.
