Data Sheet
Reading the registers in the order OR1 , OR2 must be
continued until completion or until the time frame runs
out. With a new time frame a new extraction process
begins, resuming the copy operation from the
background register. During extraction the active
channels are scanned from the highest to the lowest
number (from 7 to 0). While extraction is being carried

out the time interval requirements between active ris-
ing edges of RD are minimum 5 to 13 tCK for se-
quence OR2- OR1 and minimum 3 times tCK for se-
quence OR1 - OR2. Channel 0 extraction is disabled
by a reset pulse or by writing a zero mask into the de-
vice. This clears the mask register and the background
register
