4.7. ECT connectivity recommendations

This section describes which signals to connect to a CTI in the ECT in a system based on an ARM7, ARM9, or ARM11 processor.

The recommendations ensure that:

ECT support by development tools might only extend to naming the inputs and outputs and enabling their connection to be programmed, or it might program the ECT automatically for example for certain predefined profiling tasks.

If extra trigger inputs and outputs are required then you can use a second CTI.

Note

  • The inclusion of signals in this document does not constitute a commitment by ARM to provide features in their development tools that specifically use those signals.

  • When you require more trigger signals through ASICCTL, the recommended connections should be provided when ASICCTL is set to 0x00.
