Table 12-2. Required Idle Cycles Between Commands
Notes:
Document #: 38-02040 Rev. *F
13. When the register being read is SSR/SRR and it matches the target location of the previous search, a READ operation cannot be issued for 2+TLSZ idle cycles
14. The SRAM operation needs to insert idle cycles to avoid SADR bus contention with previous SEARCH.
x72/x144 = 1 Cycle
x72/x144 = 1 Cycle
to avoid reading the old value. Otherwise there is no idle cycle requirement.
x288 = 2 Cycles
