ITLB Miss Exception
ITLB Protection 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.
