6.5 Emulator Connection Without Signal Buffering for the DSP
Figure 6-5 shows the connection between the DSP and JTAG header for a single-processor configuration.
If the distance between the JTAG header and the DSP is greater than 6 inches, the emulation signals
must be buffered. If the distance is less than 6 inches, buffering is typically not needed.
Figure 6-5 shows
the simpler, no-buffering situation. For the pullup/pulldown resistor values, see the pin description section.
