on the falling edge of the master clock, with the pixel
clock rising on the subsequent rising edge of the mas-

pixel's data and returns LOW on the same master clock
falling edge as the end of the output of the last valid
pixel's data.
FRA ME_V A LID goes HIGH 6 pixel clocks prior to the
time that the first LINE_V ALID goes HIGH. It returns
LOW at a time corresponding to 6 pixel clocks after the
last LINE_V A LID goes LOW .
