4.5.1 Common Input Event List
Table 4-8 lists the input events for the MCU event fabric. The sources for these events are considered
level-triggered active-high.
Table 4-8. MCU Event Fabric Input Events
Event No. Event Enum. Description
0x0 NONE Always inactive
Event selected by AON_EVENT MCU event selector,
0x1 AON_PROG0
[AON_EVENT:EVTOMCUSEL.AON_PROG0_EV]
Event selected by AON_EVENT MCU event selector,
0x2 AON_PROG1
[AON_EVENT:EVTOMCUSEL.AON_PROG1_EV]
Event selected by AON_EVENT MCU event selector,
0x3 AON_PROG2
[AON_EVENT:EVTOMCUSEL.AON_PROG2_EV]
Edge detect event from IOC. Configured by the
0x4 AON_GPIO_EDGE
[IOC:IOCFGn.EDGE_IRQ_EN] and [IOC:IOCFGn.EDGE_DET] settings
A complete byte transfer event from the SPIS. Equivalent to the
0x5 AON_SPIS_BYTE_DONE
[SPIS:GPFLAGS.BYTE_DONE] flag
0x6 AON_SPIS_CS SPIS chip-select event. Equivalent to the [SPIS:GPFLAGS.CS] flag
Event from AON_RTC controlled by the
0x7 AON_RTC_COMB
[AON_RTC:CTL.COMB_EV_MASK] setting
0x8 I2S_IRQ Interrupt event from I2S
0x9 I2C_IRQ Interrupt event from I

AUX combined event, the corresponding flag register is here
0xB AUX_COMB
[AUX_EVCTL:EVTOMCUFLAGS.*]
0xC GPT2A GPT2A interrupt event, controlled by [GPT2:TAMR.*]
0xD GPT2B GPT2B interrupt event, controlled by [GPT2:TBMR.*]
0xE GPT3A GPT3A interrupt event, controlled by [GPT3:TAMR.*]
0xF GPT3B GPT3B interrupt event, controlled by [GPT3:TBMR.*]

0x11 GPT0B GPT0B interrupt event, controlled by [GPT0:TBMR.*]
0x12 GPT1A GPT1A interrupt event, controlled by [GPT1:TAMR.*]
0x13 GPT1B GPT1B interrupt event, controlled by [GPT1:TBMR.*]
DMA done for software-triggered UDMA channel 0, see
0x14 DMA_CH0_DONE
[UDMA0:SOFTREQ.*]
FLASH controller error event, the status flags are
0x15 FLASH [FLASH:FEDACSTAT.FSM_DONE] and
[FLASH:FEDACSTAT.RVF_INT]
DMA done for software-triggered UDMA channel 18, see
0x16 DMA_CH18_DONE
[UDMA0:SOFTREQ.*]

0x18 WDT_IRQ Watchdog interrupt event, controlled by [WDT:CTL.INTEN]
RFC Doorbell Command Acknowledgement interrupt, equivalent to
0x19 RFC_CMD_ACK
[RFC_DBELL:RFACKIFG.ACKFLAG].
Combined RCF hardware interrupt, corresponding flag is here
0x1A RFC_HW_COMB
[RFC_DBELL:RFHWIFG.*]
Combined interrupt for CPE-generated events. Corresponding flags are
0x1B RFC_CPE_0 here [RFC_DBELL:RFCPEIFG.*]. Only interrupts selected with CPE0 in
[RFC_DBELL:RFCPEIFG.*] can trigger a RFC_CPE_0 event.
AUX software event 0, triggered by [AUX_EVCTL:SWEVSET.SWEV0],
0x1C AUX_SWEV0
also available as AUX_EVENT0 AON wake-up event.
MCU domain wake-up control [AON_EVENT:MCUWUSEL.*]
AUX domain wake-up control [AON_EVENT:AUXWUSEL.*]
AUX software event 1, triggered by [AUX_EVCTL:SWEVSET.SWEV1],
0x1D AUX_SWEV1
also available as AUX_EVENT2 AON wake-up event.
