State Sequencer Flag Bits — The SSF bits indicate in which state the State Sequencer is in currently. During a debug session
on each transition to a new state these bits are updated. If the debug session is ended by software clearing the ARM bit, then
these bits retain their value to reflect the last state of the state sequencer before disarming. If a debug session is ended by an
internal event, then the state sequencer returns to state 0 and these bits are cleared to indicate that state0 was entered during
the session. On arming the module the state sequencer enters state1 and these bits are forced to SSF[2:0] = 001. See
Table
Trace Source Control Bit — The TSOURCE bit enables a tracing session given a trigger condition. If the MCU system is
secured, this bit cannot be set and tracing is inhibited.
This bit must be set to read the trace buffer.
0 Debug session without tracing requested
1 Debug session with tracing requested
Trace Mode Bits — See
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. In Pure PC mode the program
counter value for each instruction executed is stored. See
Trigger Align Bit — This bit controls whether the trigger is aligned to the beginning or end of a tracing session.
0 Trigger at end of stored data
1 Trigger before storing data
