Table 5-1362 shows Wake-up Sources in each low power mode.
MCU-ONLY state is not considered as a state that needs a wake-up source as processor is alive. A72SS and/or R5FSS can be in WFI and any interrupt which is routable to R5F or WKUP_DMSC0 could cause exit from this state.
Power Modes | Wake-up source |
---|---|
SoC-OFF | MCU_PORz. |
SuspendToRAM | TBD |
DeepSleep | WKUP_DMSC0 Timers (any), WKUP_UART0, WKUP_GPIO0, WKUP_GPIO1, WKUP_I2C . |
CPD-OFF | WKUP_GPIO0, WKUP_GPIO1, WKUP_UART0, WKUP_I2C0, WKUP_TIMERs. All instances of the following peripherals in MCU domain - UART, I2C, SPI, MCAN, Timers. |
Standby | All peripherals with interrupts routed to GIC. |
