If implemented, the VTOR indicates the offset of the vector
table base address from memory address 0x00000000
.
See the register summary in Table 4.12 for its attributes.
The bit assignments are:
Bits | Name | Function |
---|---|---|
[31:7] | TBLOFF | Vector table base offset field. It contains bits[31:7] of the offset of the table base from the bottom of the memory map. |
[6:0] | - | Reserved. |
Note
The vector table base must always be aligned to at least the number of exception vectors implemented. To ensure this, the Cortex-M0+ processor implements bit[7] (the least significant bit of TBLOFF) as RAZ/WI.
