4.1.2
The reset vector address is fixed at H'A0000000. The other three events are assigned offsets from
the vector base address by software. Translation look-aside buffer (TLB) miss exceptions have an
offset from the vector base address of H'00000400. The vector address offset for general exception
events other than TLB miss exceptions is H'00000100. The interrupt vector address offset is
H'00000600. The vector base address is loaded into the vector base register (VBR) by software.
The vector base address should reside in P1 or P2 fixed physical address space. Figure 4.1 shows
the relationship between the vector base address, the vector offset, and the vector table.
In table 4.1, exceptions and their vector addresses are listed by exception type, instruction
completion state, relative acceptance priority, relative order of occurrence within an instruction
execution sequence and vector address for exceptions and their vector addresses.
