5.3.2
When an address error occurs, the bus cycle in which the address error occurred ends. When the
executing instruction then finishes, address error exception processing starts up. The CPU operates
as follows:
1. The status register (SR) is saved to the stack.
2. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
3. The exception service routine start address is fetched from the exception processing vector

5.4.1
Table 5.6 shows the sources that start up interrupt exception processing. These are divided into
NMI, user breaks, IRQ and on-chip peripheral modules.
Table 5.6
Each interrupt source is allocated a different vector number and vector table offset. See section 6,
Interrupt Controller, and table 6.3, Interrupt Exception Processing Vectors and Priorities, for more
information on vector numbers and vector table address offsets.
