13.3. Cortex-A15 CTI

In the Cortex-A15 processor, CTI operates in the PCLKDBG domain and synchronizes the trigger inputs and outputs to PCLKDBG where required. Handshaking is required for all trigger outputs. Because the simplified CTM is implemented in the same clock domain, synchronization and handshaking is not required for channel interface. In addition, APB synchronization is not required. All the trigger inputs are masked by internal NIDEN. Only the trigger output signals EDBGRQ, CTIIRQ and DBGRESTART are masked by internal DBGEN.
