*: Depending on the low-power consumption mode, the reset issue from the internal resource is not included in the
recovery cause.
Notes:
− The return factor is different in each low power consumption mode.
See Chapter 6: Low Power Consumption Mode and Operations of Standby Modes in FM4 Family Peripheral Manual
Main Part (002-04856).
− The recovery process is unique for each operating mode. See Chapter 6: Low Power Consumption Mode in FM4 Family
Peripheral Manual Main Part (002-04856).
− When the power-on reset/low-voltage detection reset, they are not included in the return factor. See 12.4.8 Power-On
Reset Timing.
− In recovering from reset, CPU changes to High-speed Run mode. In the case of using the main clock and PLL clock,
they need further main clock oscillation stabilization wait time and oscillation stabilization wait time of Main PLL clock.
− Internal resource reset indicates Watchdog reset and CSV reset.
