Recommended JTAG Circuitry for Debug with Intel XScale® Microarchitecture

Certain restrictions exist in order to use JTAG based debuggers with the Intel XScale® microarchitecture (ARM* Architecture compliant). This is primarily due to the Tap Controller reset requirements of the Intel® 80200 processor with Intel XScale microarchitecture and the reset requirements of specific JTAG debuggers. The following sections outline these requirements along with suggestions for circuitry to alleviate potential problems.
