Register 32: Vector Table Offset (VTABLE), offset 0xD08
Note: This register can only be accessed from privileged mode.
The VTABLE register indicates the offset of the vector table base address from memory address
0x0000.0000.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Vector Table Base
Value Description
0 The vector table is in the code memory region.
1 The vector table is in the SRAM memory region.

R/W
0x000.00 Vector Table Offset
When configuring the OFFSET field, the offset must be aligned to the
number of exception entries in the vector table. Because there are 54
interrupts, the offset must be aligned on a 512-byte boundary.
