Description
port. PIPESTAT[2:0], TRACESYNC, and TRACEPKT[3:0] signals are
referenced to the rising edge of the trace clock. This clock is not
generated by the ETM block. It is to be derived from the system clock.
The clock should be balanced to provide sufficient hold time for the
trace data signals. Half rate clocking mode is supported. Trace data
signals should be shifted by a clock phase from TRACECLK. Refer to
Figure 3.14 page 3.26 and figure 3.15 page 3.27 in "ETM7 Technical
Reference Manual" (ARM DDI 0158B) , for example circuits that
implements both half-rateclocking and shifting of the trace data with
respect to the clock. For TRACECLK timings refer to section 5.2 on
page 5-13 in "Embedded Trace Macrocell Specification" (ARM IHI
0014E) .

are eight bits in length. A packet is output over two cycles. In the first
cycle, Packet[3:0] is output and in the second cycle, Packet[7:4] is
