Debug module interface access register (dmi) the dmi register allows access to the debug module interface (dmi). This debug transport module is based around a normal jtag test access port (tap). This debug transport module is based around a normal jtag test access port (tap).

The read value of the dtm dmi.
The entire document provides features that are useful for external debug.
The jtag standard defines a test access port (tap) that can be used to read and write a few custom registers, which can be used to communicate with debug hardware in a component. Likewise, it examines the dout value of the transaction item (i.e. It uses the jtag dtm ral model to parse the dtm dmi register fields from these writes and reads. The jtag tap allows access to arbitrary jtag registers by first selecting one using the jtag instruction register.
