Section 20 Power-Down Modes
20.8 Usage Notes
20.8.1 I/O Port Status
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.
20.8.2 Current Dissipation during Oscillation Stabilization Wait Period
Current dissipation increases during the oscillation stabilization wait period.
20.8.3 DTC Module Stop
Depending on the operating status of the DTC, MSTPA6 bit may not be set to 1. Setting of the
DTC module stop mode should be carried out only when the respective module is not activated.
For details, refer to section 8, Data Transfer Controller (DTC).
20.8.4 On-Chip Supporting Module Interrupt
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 DTC activation source.
Interrupts should therefore be disabled before entering module stop mode.
20.8.5 Writing to MSTPCR
MSTPCR should only be written to by the CPU.
