2.5.5
When using high-speed communications, streaming serial trace is possible using the
device SPI/UART and pins 7 (DAT) and 8 (CLK). Figure 2-10 shows these additional
connections. As with pins 4 (PBD) and 5 (PGC) (Section 2.5.4 “Circuits That Will
Prevent the Emulator From Functioning”), do not use pull-ups, capacitors or diodes.

2.5.6
Streaming parallel trace is possible using a device I/O port and the emulator logic probe
connector. This provides greater trace speed and data quantity, but limits
emulator-to-target distance by the length of the parallel cable. Figure 2-11 shows these
additional connections.
FIGURE 2-11:
For this trace configuration, seven (7) lines of data and one (1) line for clock are
transmitted (see Section 7.5.4 “Logic Probe/External Trigger Interface”.)
As with pins 4 (PBD) and 5 (PGC) (Section 2.5.4 “Circuits That Will Prevent the
Emulator From Functioning”), do not use pull-ups, capacitors or diodes. However, to
use probe pins as inputs, you must provide the circuitry to drive them. Unused pins
should either be pulled up or grounded. Floating pins may produce false triggers.
For more on this type of trace, see Section 5.5.2 “I/O Port Trace”.
