Data Read Address Exception
Illegal Opcode
Unimplemented Instruction
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.
The Data Read Address Error exception is generated if the address of a data memory read has
an illegal alignment.
