#### TRIN<n>, bit [n], for n = 31 to 0

Trigger input <n> status.

Bits [31:N] are RAZ. N is the number of CTI triggers implemented as defined by the CTIDEVID.NUMTRIG field.

TRIN<n> | Meaning
--- | ---
0b0 | Input trigger n is inactive.
0b1 | Input trigger n is active.

Not implemented and not-connected input triggers are always inactive.

It is IMPLEMENTATION DEFINED whether an input trigger that does not support multicycle events can be observed as active.

## Accessing CTITRIGINSTATUS

#### CTITRIGINSTATUS can be accessed through the external debug interface:

Component | Offset | Instance
--- | --- | ---
CTI | 0x130 | CTITRIGINSTATUS

Accesses on this interface are RO.
