15.3. CoreSight Debug and Trace Features

The CoreSight* debug and trace system provides the following features:
  • Supports debug:
    • Supports debug access port (DAP) to allow the host to connect to the debugger through the JTAG
    • Multiple debug APB access for debug interface
    • Debug reset: can be initiated using software internally or externally through JTAG via the Arm DAP SWJ-DP
  • Supports trace:
    • System Trace Macrocell (STM)
    • NoC Trace (PSS NOC and MPFE NOC), has the ability to trace packets, collect statistics, and log errors
    • AMBA Trace Bus (ATB)
    • Trace Port Interface Unit (TPIU)
    • Embedded Trace Router (ETR)
    • Capability for the following components to trigger each other through the embedded cross-trigger system:
      • Cross Trigger Interface (CTI): supports 32 trigger inputs and outputs with a single component instance
      • Cross Trigger Matrix (CTM): supports 33 CTI or CTM connections without cascading
      • Supports CTI-GT, CTI-NOC, CTI-5, CTI-FPGA, and CTI-MPU.
