In the event of contention with a bus request from an external bus master when a transition is
made to software standby mode, the BACK and strobe states may be indeterminate after the
transition to software standby mode (see figure 6.36).
When software standby mode is used, the BRLE bit should be cleared to 0 in BRCR before
executing the SLEEP instruction.
