Section 26 Power-Down Modes
26.5
26.5.1
In software standby mode, I/O port states are retained. Therefore, there is no reduction in current
dissipation for the output current when a high-level signal is output.
26.5.2
Current dissipation increases during the oscillation stabilization standby period.
26.5.3
Depending on the operating status of the EXDMAC, DMAC, or DTC, the MSTP12 to MSTP14
may not be set to 1. Setting of the EXDMAC, DMAC, or DTC module stop state should be carried
out only when the respective module is not activated.
For details, see section 9, EXDMA Controller (EXDMAC), section 8, DMA Controller (DMAC),
and section 10, Data Transfer Controller (DTC).
Note: The EXDMAC is not supported by the H8S/2425 Group.
26.5.4
Relevant interrupt operations cannot be performed in the module stop state. Consequently, if the
module stop state is entered when an interrupt has been requested, it will not be possible to clear
the CPU interrupt source or the DMAC or DTC activation source.
Interrupts should therefore be disabled before entering the module stop state.
Note: The EXDMAC is not supported by the H8S/2425 Group.
26.5.5
MSTPCR, EXMSTPCR, and RMMSTPCR should only be written to by the CPU.
