25.4.12.3. FPGA-CTI

The FPGA-CTI allows the FPGA to send and receive triggers from the debug system.
The FPGA Cross-trigger interface directly drives a CoreSight Cross Trigger Interface (CTI). The CTI provides clock crossing capabilities.
Table 219.   FPGA-CTI Signal Description Table The following table lists the signal descriptions between the FPGA-CTI and FPGA.
Signal Description
h2f_cti_trig_in[8] Trigger input from FPGA
h2f_cti_trig_in_ack[8] ACK signal to FPGA
h2f_cti_trig_out[8] Trigger output to FPGA
h2f_cti_trig_out_ack[8] ACK signal from FPGA
