R7F701278 (RH850/C1M-A1) interrupt service routine not working
Hi, I am working on this microcontroller. It does not have support by smart configurator. Hence, I am using smart configurator for RH850/C1M-A2 (R7F701275) to generate driver files as the H/W and S/W manual is the same. I have configured OS timer OSTM0 ...

RH850/C1M-A: What kind of benefits would I get by using the built-in RDC in the C1M-Ax?
By reducing the number of parts, the PCB area cost can be reduced. In addition, the distinctive functions of the built-in RDC can be used. (Collaborative operation with the EMU, synchronized operation with the excitation signal, error detection, etc.)
