Note:
25.2
Figure 25.1 shows the enabled mode transition diagram. The mode transition from program
execution state to program halt state is performed by the SLEEP instruction. The mode transition
from program halt state to program execution state is performed by an interrupt. The STBY input
causes a mode transition from any state to hardware standby mode. The RES input causes a mode
transition from a state other than hardware standby mode to the reset state. Table 25.2 shows the
LSI internal states in each operating mode.
