Description
NTBF -NanoTrace Buffer Full
This bit is set if Debug Mode is entered because
the Memory Service Unit has signalled that the
NanoTrace Buffer is full. This bit is cleared when
Debug Mode is exited.
EXB -External Breakpoint
This bit is set if Debug Mode was entered due to
an event on the EVTI pin. This bit is cleared when
Debug Mode is exited.
DBA - Debug Acknowledge
This bit is set if Debug Mode was entered due to
setting the Debug Request or ABORT bit in the
DC register. This bit is cleared when Debug Mode
is exited.
BOZ - Break on Opcode Zero
This bit is set if Debug Mode was entered due to
opcode 0x0000 being executed. This bit is cleared
when Debug Mode is exited.
INC - Instruction Complete
0: The CPU is executing one or more instructions,
or is not in OCD Mode.
1: The CPU is in OCD Mode and is not executing
any instructions.
BP - Breakpoint Status
The BP bits identify which hardware breakpoint
caused Debug Mode to be entered:
BP[0]: BP0A
BP[1]: BP0B
BP[2]: BP1A
BP[3]: BP1B
BP[4]: BP2A
BP[5]: BP2B
BP[6]: BP3A
BP[7]: BP3B
These bits are cleared when Debug Mode is
exited.
DBS - Debug Status
DBS is set when the CPU is in OCD Mode,
otherwise cleared. This bit stays cleared also
when the CPU operates in Monitor Mode.
