Field Value Description
Reserved 0 Reserved. Reads return 0.
index n Entry valid tag for index n. See Table 12-12. This is the 4-bit key that determines whether the current
entry in CAM is occupied or not. A write (privilege mode) to A0h to 11Ch in diagnostic mode or
functional mode does not only update the CAM content in corresponding index but also updates the
corresponding bit field in the entry valid tags registers CAM_INDEXn.
The index has a self correction mechanism as follows:
• Key active if valid key = 1010 or 1011 or 1000 or 1110 or 0010
• Key inactive if valid key = 0101 or 0100 or 0111 or 1101 or 0001
