16.3
16.3.1
In software standby mode, 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.
16.3.2
Current consumption increases during the oscillation stabilization standby period.
16.3.3
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 activation source. Interrupts should therefore be disabled before entering module
stop mode.
16.3.4
MSTPCR should only be written to by the CPU.
