Restriction: Applicable Usage: The usage which meets to (1) and (2) at the same timing is applicable to the restriction. (1) The instruction codes which addresses 001FFFCH to 0020000H are executed continuously. (2) Pipeline disorder (Note) is generated. Note: The pipeline becomes disordered caused by the following factors. 1. Alignment hazard 2. Referencing execution result of load instruction 3. Referencing execution result of multiply instruction 4. Referencing execution result of LDSR instruction for EIPC and FEPC 5. Access of On-chip peripheral I/O register For details of pipeline disordered, please see User’s manual “V850ES 32-Bit Microprocessor Core Architecture” (U15943E). Detail of Restriction: In the case of Applicable Usage, CPU executes the wrong instruction code. (Example) The pipeline disordered is generated by Alignment hazard: In this case, the instruction b will not be executed correctly. And wrong instruction code is executed. |
