WIR mode is latched from boot mode (see Section 33.3.2, Boot Modes) and allows the user to hold a secondary TAP module in reset state when a reset is applied (and thus, extend the reset). This mode lets the user control the following system level activities:
WIR mode extends only the processor reset. During reset extension, the debugger can still access modules such as L2 memory and MMU, even if they are embedded in the device subsystem affected by WIR.
When the debugger task is complete, the DTC releases the subsystem reset by programming the corresponding ICEPick TAP control register.
