*: Internal resource reset 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 depend 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.
