Exception Processing
The MC68060 supports a 1024-byte vector table containing 256 exception vectors (see
Table 8-1). Motorola defines the first 64 vectors and reserves the other 192 vectors for user-
defined interrupt vectors. External devices can use vectors reserved for internal purposes
at the discretion of the system designer. External devices can also supply vector numbers
for some exceptions. External devices that cannot supply vector numbers use the autovec-
tor capability, which allows the MC68060 to automatically generate a vector number.

8.2 INTEGER UNIT EXCEPTIONS
The following paragraphs describe the external interrupt exceptions and the different types
of exceptions generated internally by the MC68060 integer unit. The following exceptions
are discussed:
8-4
For the Access Fault exception, refer to 8.4.4.1 Program Counter (PC) .
“fault” refers to the PC of the instruction that caused the exception.
“next” refers to the PC of the next instruction that follows the instruction that caused the fault.
Refer to Section 6 Floating-Point Unit .
