S12S Debug Module (S12SDBG)
BDM: Background Debug Mode
S12SBDM: Background Debug Module
DUG: Device User Guide, describing the features of the device into which the DBG is integrated.
WORD: 16 bit data entity
Data Line: 20 bit data entity
CPU: S12SCPU module
DBG: S12SDBG module
POR: Power On Reset
Tag: Tags can be attached to CPU opcodes as they enter the instruction pipe. If the tagged opcode reaches
the execution stage a tag hit occurs.
8.1.2
The comparators monitor the bus activity of the CPU module. A match can initiate a state sequencer
transition. On a transition to the Final State, bus tracing is triggered and/or a breakpoint can be generated.
Independent of comparator matches a transition to Final State with associated tracing and breakpoint can
be triggered immediately by writing to the TRIG control bit.
The trace buffer is visible through a 2-byte window in the register address map and can be read out using
standard 16-bit word reads. Tracing is disabled when the MCU system is secured.

This document is valid for the S12G96 and the S12G128 device. All information related to other devices is preliminary.
Three comparators (A, B and C)
— Comparators A compares the full address bus and full 16-bit data bus
— Comparator A features a data bus mask register
— Comparators B and C compare the full address bus only
— Each comparator features selection of read or write access cycles
— Comparator B allows selection of byte or word access cycles
— Comparator matches can initiate state sequencer transitions
Three comparator modes
— Simple address/data comparator match mode
— Inside address range mode, Addmin ≤ Address ≤ Addmax
— Outside address range match mode, Address < Addmin or Address > Addmax
Two types of matches
— Tagged — This matches just before a specific instruction begins execution
— Force — This is valid on the first instruction boundary after a match occurs
Two types of breakpoints
