Overview
Description
The R8C/1B Group is supported only for customers who have already adopted these products. The RL78/G12 Group is recommended for new designs.
These MCUs are fabricated using the high-performance silicon gate CMOS process, embedding the R8C/ Tiny Series CPU core, and is packaged in a 20-pin molded-plastic LSSOP, SDIP or a 28-pin plastic molded HWQFN. 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/1B Group has on-chip data flash ROM (1KB × 2 blocks). The difference between the R8C/1A Group and R8C/1B Group is only the presence or absence of data flash ROM. Their peripheral functions are the same.

(R8C) Are there any hardware precautions for accurate A/D conversion?
In order to perform A/D conversion, it is necessary to fully charge the internal capacitor, but if the impedance of the A/D conversion target is high, the discharge and charge will take time and the conversion value will not be accurate. For correct A/D ...

Do I need to rewrite the boot ROM area using MI6C Flash Starter?
Rewriting of the boot ROM area is unnecessary. This is because M3A-0806 performs programming using the standard boot program which was programmed into the boot ROM area when it was shipped. (#104963)

Please tell me how to set the option function register in detail.
There are three methods for setting the option function select register using the C complier package M3T-NC30WA: Using the load module converter (lmc30 -R8C) -OFSREGX (or -PROTECTX) option Using assembler directive command .OFSREG (or .PROTECT) By assembly programming The load module converter option and directive command depend on the ...
