Reserved (in some devices these bits are part of the TBLOFF bitfield as explained below).
[29(31):7] TBLOFF
Vector table base offset field. It contains bits[29:7] (bits[31:7] for Cortex-M3 revision r2p1 and
later) of the offset of the table base from the bottom of the memory map. Table 1.1 (p. 5) shows
the Cortex-M3 revision number for the EFM32 device series.
Note
Bit[29] (bit 31 in Cortex-M3 revision r2p1 and later) determines whether the vector table
is in the code or SRAM memory region:
0 = code
1 = SRAM.
Bit[29(31)] is sometimes called the TBLBASE bit.
[6:0]
-
Reserved.
When setting TBLOFF, you must align the offset to the number of exception entries in the vector table.
The recommended alignment is 64 words, which covers all EFM32 interrupts and the 16 internal Cortex-
M3 exceptions. If you require 16 interrupts or less, the alignment can be set to 32 words.
Note
Table alignment requirements mean that bits[6:0] of the table offset are always zero.
4.3.6 Application Interrupt and Reset Control Register
The AIRCR provides priority grouping control for the exception model, endian status for data accesses,
and reset control of the system. See the register summary in Table 4.12 (p. 94) and Table 4.17 (p.
99) for its attributes.
To write to this register, you must write 0x5VA to the VECTKEY field, otherwise the processor ignores
the write.
The bit assignments are:
On read: VECTKEYSTAT
On writ e: VECTKEY

priority from subpriority, see Section 4.3.6.1 (p. 100) .
