ColdFire Core
The 16-bit format/vector word contains 3 unique fields:
3-12
• A 4-bit format field at the top of the system stack is always written with a value of 4, 5, 6,
• There is a 4-bit fault status field, FS[3:0], at the top of the system stack. This field is defined
• The 8-bit vector number, vector[7:0], defines the exception type and is calculated by the
or 7 by the processor indicating a two-longword frame format. See
for access and address errors only and written as zeros for all other types of exceptions. See
Table
processor for all internal faults and represents the value supplied by the interrupt controller
in the case of an interrupt. Refer to
3-9.
