3 Flow Director: Update Filter Flow Limitation

Parameters update of an existing Flow Director filter can be done by the Update Filter Flow as described

in the Datasheet.

It should be noted that the Update Filter Flow process requires internal memory space used to store

temporary data until the update concludes. Therefore, Update Filter Flow can be used only if the

maximum number of allocated flow director filters (as defined by FDIRCTRL.PBALLOC) is not fully used.

For example, if FDIRCTRL.PBALLOC=01b, memory is allocated for 2K-1 perfect filters. In this case, the

Update Filter Flow can be used only if not more than 2K-2 filters were programmed.

4 Bit 16 of CTRL_EXT Register Must Be Set
