ITLB Miss Exception
ITLB Protection Exception
Breakpoint Exception
The ITLB Miss exception is generated when no TLB entry matches the instruction memory
address, or if the Valid bit in a matching entry is 0.
The ITLB Protection exception is generated when the instruction memory access violates the
access rights specified by the protection bits of the addressed virtual page.
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.
