描述
The R8C/25 Group is supported only for customers who have already adopted these products. The RL78/G14 Group is recommended for new designs.
These MCUs are fabricated using a high-performance silicon gate CMOS process, embedding the R8C/Tiny Series CPU core, and are packaged in a 52-pin molded-plastic LQFP or a 64-pin molded-plastic FLGA. It implements sophisticated instructions for a high level of instruction efficiency. With 1Mb of address space, they are capable of executing instructions at high speed. Furthermore, the R8C/25 Group has on-chip data flash (1KB x 2 blocks). The difference between the R8C/24 Group and R8C/25 Group is only the presence or absence of data flash. Their peripheral functions are the same.

(CPU) M16C/60系列的指令中，R8C族不能使用哪些指令？
R8C族不能使用JMPS与JSRS指令。JMPS与JSRS指令将程序跳转到F0000h~FFFFFh内的程序区，R8C族中这一区域无ROM，因此不能使用。
