4.32.1.4
The DBG module can be used in all MCU functional modes.
During BDM hardware accesses and whilst the BDM module is active, CPU monitoring is disabled. When the CPU enters active
BDM Mode through a BACKGROUND command, the DBG module, if already armed, remains armed.
The DBG module tracing is disabled if the MCU is secure, however, breakpoints can still be generated

Four trace modes
— Normal: change of flow (COF) PC information is stored (see
— Loop1: same as Normal but inhibits consecutive duplicate source address entries
— Detail: address and data for all cycles except free cycles and opcode fetches are stored
— Compressed Pure PC: all program counter addresses are stored
4-stage state sequencer for trace buffer control
— Tracing session trigger linked to Final State of state sequencer
— Begin and End alignment of tracing to trigger
