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 | |
| [4] | DMA single request selected by EVTSVT.DMACH3SEL | |
| [3] | DMA burst request selected by EVTSVT.DMACH4SEL | |
| [2] | DMA single request selected by EVTSVT.DMACH4SEL | |
| [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 |
