Note:
13. The NSE density determines to which SADR field EADR[2:0] is mapped. In Ayama10128, SADR[23:21] gets EADR[2:0]; In Ayama10256, SADR[24:22] gets
14. When issuing x288 and x576 searches, there are multiple A and B cycle. In this scenario the CMPR[3:0] must change for every B-cycle of the x288/x576 search,

if that key is to be learnt at a later stage. If the search key need not be learnt, the CMPR[3:0] is a don’t care. Similarly GMR values could vary depending which
part of the key needs to be masked for x288 and x576 searches.
