Fetch accesses from the CPU can be protected by setting the FETCHPROTx bit of the specific register to 1. If fetch access is done by the CPU to a memory where CPU fetch protection is enabled, a fetch protection violation occurs.
If a fetch protection violation occurs, the violation results in an ITRAP for the CPU. A flag gets set in the appropriate access violation flag register, and the memory address for which the access violation occurred, gets latched into the appropriate CPU fetch access violation address register.
