All fault signals are sent to a flag mux component. There are four important FLAGMUX registers:
The two L3_FLAGMUX_MASK registers mask bit 0 or bit 1 of the flag inputs, and the L3_FLAGMUX_REGERR registers read input errors. Each register is dedicated to reporting the bit corresponding to the register number.
Table 14-24 describes the mapping of the flags to the corresponding sources.
