ITLB Miss Exception
Instruction Address Exception
ITLB Protection Exception
Breakpoint Exception
The Instruction Address Error exception is generated if the generated instruction memory
address has an illegal alignment.
The ITLB Miss exception is generated when the MPU is enabled and the instruction memory
access does not hit in any regions. Used only if an MPU is present.
The ITLB Protection exception is generated when the instruction memory access violates the
access rights specified by the protection region in which the address lies. Used only if an MPU is
present.
The Breakpoint exception is issued when the OCD breakpoint input line to the CPU is aseerted,
and SREG[DM] is cleared.
When entering the exception routine, RAR_DBG points to the breakpoint instruction, and the
CPU will enter Debug mode. 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 con-
trol from the debugger back to the CPU, resuming normal execution.
