Breakpoint Exception
Illegal Opcode
Unimplemented Instruction
The Breakpoint exception is issued when a breakpoint instruction is executed, or the OCD
breakpoint input line to the CPU is asserted, and SREG[DM] is cleared.
An external debugger can optionally assume control of the CPU when the Breakpoint Exception
is executed. The debugger can then issue individual instructions to be executed in Debug mode.
Debug mode is exited with the retd instruction. This passes control from the debugger back to
the CPU, resuming normal execution.
This exception is issued when the core fetches an unknown instruction, or when a coprocessor
instruction is not acknowledged. When entering the exception routine, the return address on
stack points to the instruction that caused the exception.
This exception is issued when the core fetches an instruction supported by the instruction set
but not by the current implementation. This allows software implementations of unimplemented
instructions. When entering the exception routine, the return address on stack points to the
instruction that caused the exception.
