This section describes the trigger inputs and outputs that are available to the CTI.
Table 13.1 shows the CTI inputs.
Table 13.1. Trigger inputs
| CTI input | Name | Description |
|---|---|---|
| 0 | DBGTRIGGER, pulsed | Pulsed on entry to debug state |
| 1 | PMUIRQ[a] | PMU generated interrupt |
| 2 | EXTOUT[0] | PTM external output |
| 3 | EXTOUT[1] | PTM external output |
| 4 | COMMTX | Debug communication transmit channel is empty |
| 5 | COMMRX | Debug communication receive channel is full |
| 6 | PTMTRIGGER | PTM trigger |
| 7 | - | - |
[a] This signal is the same as nPMUIRQ with inverted polarity. | ||
Table 13.2 shows the CTI outputs.
Table 13.2. Trigger outputs
| CTI output | Name | Description |

| 0 | EDBGRQ | Causes the processor to enter debug state |
| 1 | EXTIN[0] | PTM external input |
| 2 | EXTIN[1] | PTM external input |
| 3 | EXTIN[2] | PTM external input |
| 4 | EXTIN[3] | PTM external input |
| 5 | CTIEXTTRIG | CTI external trigger |
