6.5JTAG Emulator Support

The IQ31244 provides a JTAG debugger interface at J5. This interface is compatible with the Wind River* visionPROBE*. The JTAG emulator interface connects primarily through the JTAG port of the Intel® 80321 I/O Processor and can assert a reset to the 80321. The JTAG emulator header definition (20-pin standard ARM* connector) is shown in Table 20.
