Global Error Routing; L3 External Input Flags - Texas Instruments OMAP36 Series Technical Reference Manual

L3 Interconnect
MPU SS
DSP SS
In addition to the SResp qualifier error reporting, some external targets use an SError signal to indicate
that an internal error has occurred. Some resetting action may be required before any new request can be
accepted, depending on the module and on the error itself. These signals are routed as flags internally to
the L3. Table 9-28
interconnect, and aggregated to the L3 application error flag.
