Mode Transitions And Lsi States - Renesas H8S Series Hardware Manual

Section 24 Power-Down Modes
MSTPCRB specifies on-chip peripheral modules to shift to module stop mode in module units.
Each module can enter module stop mode by setting the corresponding bit to 1.

Mode Transitions and LSI States

Figure 24.1 shows the possible 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 24.2 shows the
LSI internal states in each operating mode.
