Trace Source Control Bits — The TSOURCE bits select the data source for the tracing session. If the MCU
system is secured, these bits cannot be set and tracing is inhibited. See
Trace Range Bits — The TRANGE bits allow filtering of trace information from a selected address range when
tracing from the S12XCPU in Detail Mode. The XGATE tracing range cannot be narrowed using these bits. To
use a comparator for range filtering, the corresponding COMPE and SRC bits must remain cleared. If the
COMPE bit is not clear then the comparator will also be used to generate state sequence triggers. If the
corresponding SRC bit is set the comparator is mapped to the XGATE buses, the TRANGE bits have no effect
on the valid address range, memory accesses within the whole memory map are traced. See
Trace Mode Bits — See
information is stored. In Loop1 Mode, change of flow information is stored but redundant entries into trace
memory are inhibited. In Detail Mode, address and data for all memory and register accesses is stored. See
Table
Trigger Align Bits — These bits control whether the trigger is aligned to the beginning, end or the middle of a
tracing session. See

TSOURCE
No range limitations are allowed. Thus tracing operates as if TRANGE = 00.
No Detail Mode tracing supported. If TRCMOD = 10, no information is stored.
