19.4.10 Operation in Standby Mode Status
Status DTC Operation
HALT mode Operable (Operation is disabled while in the low
power consumption RTC mode)
STOP mode DTC activation sources can be accepted
Note 2
SNOOZE mode Operable
Notes 1, 3
Notes 1. The SNOOZE mode can only be specified when the high-speed on-chip oscillator clock is selected as f
CLK.
2. In the STOP mode, detecting a DTC activation source enables transition to SNOOZE mode and DTC transfer.
After completion of transfer, the system returns to the STOP mode. However, since the code flash memory
and the data flash memory are stopped during the SNOOZE mode, the flash memory cannot be set as the
transfer source.
3. When an A/D conversion end interrupt is set as a DTC activation source from the A/D converter SNOOZE
mode function, release the SNOOZE mode using the A/D conversion end interrupt to start CPU processing
after completion of DTC transfer, or use a chained transfer to set the A/D converter SNOOZE mode function
again after clear the AWC bit.
19.4.11 Notes When the RAM Area Is the Source of the Data for Transfer
Make initial settings with the desired values when the RAM area is the source of the data for transfer. RAM ECC interrupts
may be produced in some cases.
19.4.12 Vector Address for High-Speed Transfer
For high-speed transfer, too, a DTC vector address allocated to each activation source is read out. For chain transfer at
high-speed, control data indicated by the DTC vector address are allocated to contiguous areas, and the next control data
are read out. For transfer other than chain transfer at high-speed, make initial settings with the desired values in the DTC
vector addresses.
