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 CPU 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 or tags. If the SRC bit is
set the comparator is mapped to the XGATE busses, corrupting the trace. See
Trace Mode Bits — See
mode, change of flow 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
Trigger Align Bits — These bits control whether the trigger is aligned to the beginning, end or the middle of a
tracing session. See

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