In normal mode tracing, the trace port signals PIPESTATA and TRACEPKTA are mapped directly onto the trace port pins of the ASIC. PIPESTATB and TRACEPKTB are not used. Both normal and half-rate clocking are supported in this mode, but half-rate clocking is recommended to allow for higher frequency tracing. To use half-rate clocking, the TPA device must be capable of capturing data on both edges of TRACECLK.

Figure 3.7 shows the timing for the normal trace port with normal clocking.

Figure 3.8 shows the timing for the normal trace port with half-rate clocking.
