system call exceptions, and breakpoint exceptions) indicate some sort of abnormal
conditions, the system tends to be reset.
error exceptions (instruction fetch/data access), the PC that caused the exception will be
stored in EPC. Therefore, returning the system by simply using ERET may cause the same
exception again.
