This register allows DSP software to identify which processor it is running on. Each of the four bits in the register correspond to a particular processor node. A node can read the status of all four bits but can only write to its own bit.

To identify its processor, the DSP program first locks the Global Shared Bus for its use by asserting TOUT0. It then reads the value of this register and stores the result. This value is toggled (inverted) and written back to the register. The register is read once again and compared to the first reading to determine which bit was changed by the write operation. Because only the bit corresponding to the node can be changed, this bit will identify the node that the application is running on. TOUT0 should then be de-asserted to release the Global Shared Bus.
