Notes: 1. Three wait states are inserted when reading the SIM, dual-port RAM, and CPM. Four wait states are inserted when reading
the SI RAM. Additional wait states may be inserted when the SHEN1-SHEN0 = 10 and one of the internal masters is
accessing an internal peripheral.
2. TS68040 Transfer Attribute Signals = SIZx, TTx, TMx, R/W, LOCK.
