描述
The R8C/23 Group is supported only for customers who have already adopted these products.
This MCU is built using the high-performance silicon gate CMOS process using the R8C CPU core and is packaged in a 48-pin plastic molded LQFP. This MCU operates using sophisticated instructions featuring a high level of instruction efficiency. With 1Mb of address space, it is capable of executing instructions at high speed. This MCU is equipped with one CAN module and suited to in-vehicle or FA networking. Furthermore, the data flash (1KB x 2 blocks) is embedded in the R8C/23 Group. The difference between R8C/22 and R8C/23 Groups is only the existence of the 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。
