Trace data widths:

  • 4 bit

  • 8 bit

  • 16 bit

  • 24 bit (not supported with RealView Trace)

  • 32 bit (supported by ETB11 only, but not with RealView Trace)

Trace port modes (non-v3 architecture):

  • Normal

  • Multiplexed

  • Demultiplexed

Trace port modes (ETMv3 only), of the form Port_speed:ETM_clock_speed:

  • 1:1

  • 1:2

  • 1:3

  • 1:4

  • 2:1

  • Use dynamic ratio modes for on-chip trace.

  • Use the implementation-defined mode, if implemented by the ASIC designer.
