Chapter 8 S12X Debug (S12XDBGV3) Module
this triggers the state sequencer into the Final State, if configured for end alignment, setting the TRIG bit
disarms the module, ending the session. If breakpoints are enabled, a forced breakpoint request is issued
immediately (end alignment) or when tracing has completed (begin or mid alignment).
8.4.3.6
In case of simultaneous triggers, the priority is resolved according to
is suppressed. It is thus possible to miss a lower priority trigger if it occurs simultaneously with a trigger
of a higher priority. The trigger priorities described in
matches, the match on the lower channel number (0,1,2,3) has priority. The SC[3:0] encoding ensures that
a match leading to final state has priority over all other matches in each state sequencer state. When
configured for range modes a simultaneous match of comparators A and C generates an active match0
whilst match2 is suppressed.
If a write access to DBGC1 with the ARM bit position set occurs simultaneously to a hardware disarm
from an internal trigger event, then the ARM bit is cleared due to the hardware disarm.
8.4.4
The state sequencer allows a defined sequence of events to provide a trigger point for tracing of data in the
trace buffer. Once the S12XDBG module has been armed by setting the ARM bit in the DBGC1 register,
