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
