is not included in return factor by the kind of Low-Power consumption mode.

Notes:

・The return factor is different in each Low-Power consumption modes.

See "CHAPTER 6: Low Power Consumption Mode and Operations of Standby Modes" in "FM3

Family PERIPHERAL MANUAL".

・When interrupt recoveries, the operation mode that CPU recoveries depends on the state before

the Low-Power consumption mode transition. See "CHAPTER 6: Low Power Consumption

Mode" in "FM3 Family PERIPHERAL MANUAL".

・The time during the power-on reset/low-voltage detection reset is excluded. See "(6) Power-on

Reset Timing" in "4. AC Characteristics" in "■ Electrical Characteristics" for the detail on the

time during the power-on reset/low -voltage detection reset.

・When in recovery from reset, CPU changes to the High-speed CR Run mode. When using the

main clock or the PLL clock, it is necessary to add the main clock oscillation stabilization wait

time or the Main PLL clock stabilization wait time.

・The internal resource reset means the watchdog reset and the CSV reset.
