Description

This function validates the bad_addr argument to an instruction-related exception handler. The function

parses the handler’s cause argument to determine whether the bad_addr register contains the exception-

causing address.

If the exception is of a type that generates a valid address in bad_addr, this function returns a nonzero

value. Otherwise, it returns zero.

If the cause register is unimplemented in the Nios II processor core, this function always returns zero.

Return

A nonzero value means bad_addr contains the exception-causing address.

Zero means the value of bad_addr is to be ignored.
