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 FM4 Family Peripheral Manual Main part
(002-04856).
− The time during the power-on reset/low-voltage detection reset is excluded to the recovery source. See (6) Power-on Reset
Timing in 13.4. AC Characteristics in 13. 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.
