S12S Debug Module (S12SDBGV2)
If a tracing session is selected by the TSOURCE bit, breakpoints are requested when the tracing session
has completed, thus if Begin aligned triggering is selected, the breakpoint is requested only on completion
of the subsequent trace (see
immediately.
If the BRK bit is set, then the associated breakpoint is generated immediately independent of tracing
trigger alignment.
6.4.7.2
If a TRIG triggers occur, the Final State is entered whereby tracing trigger alignment is defined by the
TALIGN bit. If a tracing session is selected by the TSOURCE bit, breakpoints are requested when the
tracing session has completed, thus if Begin aligned triggering is selected, the breakpoint is requested only
on completion of the subsequent trace (see
requested immediately. TRIG breakpoints are possible with a single write to DBGC1, setting ARM and
TRIG simultaneously.
6.4.7.3
If a TRIG trigger occurs after Begin aligned tracing has already started, then the TRIG no longer has an
effect. When the associated tracing session is complete, the breakpoint occurs. Similarly if a TRIG is
followed by a subsequent comparator channel match, it has no effect, since tracing has already started.
If a forced SWI breakpoint coincides with a BGND in user code with BDM enabled, then the BDM is
activated by the BGND and the breakpoint to SWI is suppressed.
6.4.7.3.1
Breakpoint operation is dependent on the state of the BDM module. If the BDM module is active, the CPU
is executing out of BDM firmware, thus comparator matches and associated breakpoints are disabled. In
addition, while executing a BDM TRACE command, tagging into BDM is disabled. If BDM is not active,
the breakpoint gives priority to BDM requests over SWI requests if the breakpoint happens to coincide
with a SWI instruction in user code. On returning from BDM, the SWI from user code gets executed.
