• TBLOFF
Vector table base offset field. It contains bits[29:7] of the offset of the table base from the bottom of the memory map.
Bit[29] determines whether the vector table is in the code or SRAM memory region:
0 = code
1 = SRAM.
Bit[29] is sometimes called the TBLBASE bit.
When setting TBLOFF, you must align the offset to the number of exception entries in the vector table. The minimum align-
ment is 32 words, enough for up to 16 interrupts. For more interrupts, adjust the alignment by rounding up to the next power
of two. For example, if you require 21 interrupts, the alignment must be on a 64-word boundary because the required table
size is 37 words, and the next power of two is 64.
Table alignment requirements mean that bits[6:0] of the table offset are always zero.
