VTOR: offset address configuration

Do I need to configure vector table offset address to 0xnnnn_n000?

In case of 0x3080(Flash region), the program jump to unexpected code.

I think it is caused by mismatching between vector number and handler address.

In case of 0x3000(Flash region), the program is working correctly.

These Flash region date are same, and are located from initial stack pointer of vector number 0.

According to reference manual, TBLOFF is assigned 31~7bit and 6~0 are reserved.

so I think 0x3080 is not wrong configuration.
