ARM Cortex-A15 MPCore Processor Technical Reference Manual

System ControlThere are two formats for this register. The current translation table format determines whichformat of the register is used. This section describes:• IFSR format when using the Short-descriptor translation table format.• IFSR format when using the Long-descriptor translation table format on page 4-80.IFSR format when using the Short-descriptor translation table formatFigure 4-33 shows the IFSR bit assignments when using the Short-descriptor translation tableformat.31 13 12 11 10 9 8 4 3 0Reserved 0ReservedFS[3:0]FS[4]ReservedExTFigure 4-33 IFSR bit assignments for Short-descriptor translation table formatTable 4-63 shows the IFSR bit assignments when using the Short-descriptor translation tableformat.Table 4-63 IFSR bit assignments for Short-descriptor translation table formatBits Name Function[31:13] - Reserved, UNK/SBZP.[12] ExT External abort type.
