4.4.7. CTI Channel to Trigger Enable Registers, CTIOUTEN0-7, 0x0A0-0x0BC

The CTI Channel to Trigger Enable Registers define which channels can generate a CTITRIGOUT output. There is one register for each of the eight CTITRIGOUT outputs. Within each register there is one bit for each of the four channels implemented. These registers affect the mapping from application trigger to trigger outputs.

Figure 4.9 shows the bit assignments.

Table 4.8 shows the bit assignments.

BitsNameDescription
[31:4]-Reserved RAZ DNM.
[3:0]TRIGOUTEN

Changing the value of this bit from a 0 to a 1 enables a channel event for the corresponding channel to generate an CTITRIGOUT output:

0 = the channel input (CTICHIN) from the CTM is not routed to the CTITRIGOUT output

1 = the channel input (CTICHIN) from the CTM is routed to the CTITRIGOUT output.

There is one bit for each of the four channels. For example in register CTIOUTEN0, enabling bit 0 enables CTICHIN[0] to cause a trigger event on the CTITRIGOUT[0] output.
