Notes: 1. Both CPUs: Indicates that exception handling is performed on both CPU0 and CPU1.
Each CPU: Indicates that exception handling is performed on CPU0 when the exception
source occurred on CPU0 or performed on CPU1 when the exception source occurred
on CPU1.
User selection A: Indicates that only CPU0, only CPU1, or both CPU0 and CPU1 can
be selected to perform exception handling.
User selection B: Indicates that only CPU0 or only CPU1 can be selected to perform
exception handling.
2. The vector numbers and vector table address offsets for each external interrupt and on-
chip peripheral module interrupt are given in table 7.4 in section 7, Interrupt Controller
(INTC).

Exception Source
Vector Table Address Calculation
Resets
Vector table address = (vector table address offset)
= (vector number) × 4
Address errors, sleep errors, register Vector table address = VBR + (vector table address offset)
bank errors, interrupts, instructions
= VBR + (vector number) × 4
Notes: 1. Vector table address offset: See table 6.3.
2. Vector number: See table 6.3.
