Interrupt Module (S12SINTV1)
7.1
Introduction
The INT module decodes the priority of all system exception requests and provides the applicable vector
for processing the exception to the CPU. The INT module supports:
•
I bit and X bit maskable interrupt requests
•
A non-maskable unimplemented op-code trap
•
A non-maskable software interrupt (SWI) or background debug mode request
•
Three system reset vector requests
•
A spurious interrupt vector
Each of the I bit maskable interrupt requests is assigned to a fixed priority level.
7.1.1
Glossary
contains terms and abbreviations used in the document.
7.1.2
Features
•
Interrupt vector base register (IVBR)
•
One spurious interrupt vector (at address vector base
1
+ 0x0080).

Description of Changes
01.02
13 Sep
2007
updates for S12P family devices:
- re-added XIRQ and IRQ references since this functionality is used
on devices without D2D
- added low voltage reset as possible source to the pin reset vector
01.04
20 May
2009
added footnote about availability of “Wake-up from STOP or WAIT
by XIRQ with X bit set” feature
01.05
14 Dec
2011
Re-worded for difference of Wake-up feature between STOP and
WAIT modes.
