When the Read Only Register (ROR)has been configured by the user, thecontents of R5000~R8071 (dependson the quantity of configuration) willbe loaded from the ROR's duringeach time of power up or changingfrom STOP to RUN mode.The user can access the ROR throughthe corresponding R5000~R8071.M(2002)Write operation of functioninstructions are prohibited in thisT(256)C(256)R(3840)M2001T0T255C0C255R0M2001T0T255C0C255R0ROR area of corresponding R5000~R8071.
