10.7.2 JTAG Interface
The ZM7300 series DPMs feature the JTAG interface that can be used for programming the DPM with user-
specific configuration settings. JTAG boundary-scan capabilities are not currently supported.
JTAG-programmable DPMs have unique 5-digit identifiers listed in Table 6.
Only the DPM part numbers listed in the table can be programmed via the JTAG interface.
Note: The DPMs can be programmed via the JTAG only once. After initial programming via the JTAG, the

In order to program a DPM via the JTAG interface, the Serial Vector Format (SVF) file needs to be generated.
Click Generate SVF button in the System Configuration window shown in Figure 9. It will open the SVF Generator
window shown in Figure 21.
The window allows specifying the location of the target DPM in the JTAG chain and setting delays to generate the
appropriate Serial Vector Format file. The resulting file is used to program the DPMs through the JTAG interface.
