DSP and Microcontroller Connector Signal Mapping

Figure 3–10 describes the essential signals for the serial interface using a host
processor DSP or microcontroller. Basically, three headers J8, J9, and J10 are
used so that the user can build a customized 20-pin ribbon cable to plug into
the J9 header and easily route the signals using the wire wrap and jumper
method. This can be achieve by properly identifying the signals from the 20-pin
custom cable and connecting each to the corresponding signals indicated in
the odd-numbered pins of header J10.
