set to 1, VPED is set to 0 and
VCED set to 1. In request #2, the settings VSET = 1, VCED = 0 and VPED = 0 are used. For
request #3, all three VSET, VCED and VPED

in the MODE register. Both
modes of searching as well as searching for invalid lines are possible under microprocessor
control during cell processing.
For SW convenience and acceleration of the connection data update, write request #4 may be
extended by using the CEE and CLE bits in the MODE register. If CEE is set to 1 before writing
a pattern to a line, searching for this pattern in the CAME (and the optional second CAME) is
performed. If this pattern is already present, the command cycle is finished without writing to the
line. This failure is reported in the status register. Next, if enabled, prior to writing with CLE set
to 1, the destination line is checked to determine if it already contains a valid entry (with VCON
= 1). Writing is prevented only if a valid pattern (VCON =1) is intended to be written over a valid
entry and the failure is reported in the status field.
