Section 19 Power-Down Modes
19.9
19.9.1
In software standby mode, the I/O port states are retained. Therefore, there is no reduction in
current consumption for the output current when a high-level signal is output.
19.9.2
Current consumption increases during the oscillation settling standby period.
19.9.3
Depending on the operating state of the DMAC, bit MSTPA13 may not be set to 1. Setting of the
DMAC module stop mode should be carried out only when the DMAC is not activated.
For details, refer to section 7, DMA Controller (DMAC).
19.9.4
Relevant interrupt operations cannot be performed in module stop mode. Consequently, if module
stop mode is entered when an interrupt has been requested, it will not be possible to clear the CPU
interrupt source or the DMAC activation source. Interrupts should therefore be disabled before
entering module stop mode.
19.9.5
MSTPCRA, MSTPCRB, and MSTPCRC should only be written to by the CPU.
