Both MCU and AON event fabric structures include a feature to enable porting a set of selected internal signals to the pads for observation purposes.
The signals are grouped into several 16-bit buses, which can be selected through the DTB.SEL register. A value of zero within DTB.SEL disables this feature and only zeros are exported.
The signals that can be observed from within EVTULL are:
EVTULL.DTB[0] SEL bit | Bits | Observed signal |
0 | [15:0] | All zeros |
1 | [15:8] | All zeros |
[7] | AON_RTC_COMB event | |
[6] | AON_PMU_COMB event | |
[5] | AON_CKM_COMB event | |
[4] | AON_DBG_COMB event | |
[3] | AON_IOC_COMB event | |
[2] | AON_LPMCMP_IRQ event | |
[1] | Event selected for wakeup by EVTULL.WKUPMASK | |
[0] | Event selected for ULL NMI by EVTULL.NMISEL |
The signals that can be observed from within EVTSVT are:
EVTSVT.DTB[1:0] SEL bit field | Bits | Observed signal |
0 | [15:0] | All zeros |
1 | [15] | SYSTIM_COMB event |
[14] | LGPT0_COMB event | |
[13] | LGPT1_COMB event | |
[12] | LGPT2_COMB event | |
[11] | LGPT3_COMB event | |
[10] | UART0_COMB event | |
[9] | I2C0_IRQ event | |
[8] | SPI0_COMB event | |
[7] | ADC_COMB event | |
[6] | GPIO_COMB event | |
[5] | FLASH_IRQ event | |
[4] | AES_COMB event | |
[3] | DMA_DONE_COMB event | |
[2] | LRFD_EVT0 event | |
[1] | LRFD_EVT1 event | |
[0] | LRFD_EVT2 event | |
2 | [15] | Event selected by EVTSVT.CPUIRQ0SEL |
[14] | Event selected by EVTSVT.CPUIRQ2SEL | |
[13] | Event selected by EVTSVT.SYSTIMC1SEL | |
[12] | Event selected by EVTSVT.NMISEL | |
[11] | DMA burst request selected by EVTSVT.DMACH0SEL | |
[10] | DMA single request selected by EVTSVT.DMACH0SEL | |
[9] | DMA burst request selected by EVTSVT.DMACH1SEL | |
[8] | DMA single request selected by EVTSVT.DMACH1SEL | |
[7] | DMA burst request selected by EVTSVT.DMACH2SEL | |
[6] | DMA single request selected by EVTSVT.DMACH2SEL | |
[5] | DMA burst request selected by EVTSVT.DMACH3SEL | |

[1] | DMA burst request selected by EVTSVT.DMACH5SEL | |
[0] | DMA single request selected by EVTSVT.DMACH5SEL | |
3 | [15:4] | All zeros |
[3] | DMA burst request selected by EVTSVT.DMACH6SEL | |
[2] | DMA single request selected by EVTSVT.DMACH6SEL | |
[1] | DMA burst request selected by EVTSVT.DMACH7SEL | |
[0] | DMA single request selected by EVTSVT.DMACH7SEL |
