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

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 |
