Note: n = 2, 3
⎯ the chip enters software standby mode
⎯ the external bus is released
⎯ the RCDM bit or BE bit is cleared to 0
If a transition is made to the all-module-clocks-stopped mode in the RAS down state, the clock
will stop with RAS low. To enter the all-module-clocks-stopped mode with RAS high, the
RCDM bit must be cleared to 0 before executing the SLEEP instruction.
