8.4.7.1
The XGATE software breakpoint instruction BRK can request a CPU12X breakpoint, via the S12XDBG
module. In this case, if the XGSBPE bit is set, the S12XDBG module immediately generates a forced
breakpoint request to the CPU12X, the state sequencer is returned to state0 and tracing, if active, is
terminated. If configured for BEGIN trigger and tracing has not yet been triggered from another source,
the trace buffer contains no information. Breakpoint requests from the XGATE module do not depend
upon the state of the DBGBRK or ARM bits in DBGC1. They depend solely on the state of the XGSBPE
and BDM bits. Thus it is not necessary to ARM the DBG module to use XGATE software breakpoints to
generate breakpoints in the CPU12X program flow, but it is necessary to set XGSBPE. Furthermore, if a
breakpoint to BDM is required, the BDM bit must also be set. When the XGATE requests an CPU12X
breakpoint, the XGATE program flow stops by default, independent of the S12XDBG module.
8.4.7.2
Breakpoints can be generated when internal comparator channels trigger the state sequencer to the Final
State. If configured for tagging, then the breakpoint is generated when the tagged opcode reaches the
execution stage of the instruction queue.
If a tracing session is selected by TSOURCE, breakpoints are requested when the tracing session has
completed, thus if Begin or Mid aligned triggering is selected, the breakpoint is requested only on
completion of the subsequent trace (see
requested immediately.
If the BRK bit is set on the triggering channel, then the breakpoint is generated immediately independent
of tracing trigger alignment.
