11.3.2.2 S08 and ColdFire Exception Processing Comparison
This section presents a brief summary comparing the exception processing differences
between the S08 and V1 ColdFire processor families.
Freescale Semiconductor, Inc.
• There is a 4-bit fault status field, FS[3:0], at the top of the system stack. This field is
• The 8-bit vector number, vector[7:0], defines the exception type and is calculated by
defined for access and address errors only and written as zeros for all other
exceptions. See
the processor for all internal faults and represents the value supplied by the interrupt
controller in case of an interrupt . See
