The interrupt used for release in STOP1 mode needs to set up CPU, and needs to set updetection by INTIF.● Released by Non-Maskable Interrupt (NMI)The WDT interrupt (INTWDT0, Protect A mode only.) or the LVD interrupt (INTLVD) can perform releasefrom the Low Power Consumption modes.● Released by resetThe reset except SIWDT and OFD can perform return from all the Low Power Consumption modes.When released by reset, the registers will be initialized in NORMAL mode after release. For details, refer to"3.2.6.1. The reset factor and the reset range".● Released by SysTick interruptSysTick interrupt is available only in IDLE mode.Refer to "Interrupt" chapter of the reference manual "Exception" about the details of interrupt.Warming-up at the release of Low Power Consumption modeWarming-up may be required because of stability of an internal oscillator at the time of mode transition.When the transition from STOP1 mode to NORMAL mode is done, the internal oscillation is selectedautomatically and the warming-up timer is started. The Output of a system clock is started after warming-up timeprogress.For this reason, before executing the command which move to the STOP1 mode, set up warming-up time by[CGWUPHCR]4]>. For the setting method, refer to the "1.2.4.1. The warming-up timer for a highspeed oscillation".The following table shows the necessity of warming-up setup at the time of each Operation mode transition.Table 1.12 Warming-upOperation mode transition Warming-up setupNORMAL >>> IDLE Not required.NORMAL >>> STOP1 Not required.IDLE >>> NORMAL Not required.STOP1 >>> NORMAL Required.
