Description of Updated MCU
As the operation of the interrupt control register of the M16C/80 group MCUs has been changed, the way of resolving priority among interrupt requests in the evaluation MCU has been updated as follows:
Updated Version:
When two or more interrupt requests which have the same priority level are sampled active at the time of priority resolution, they are arbitrated in such a way that the interrupt which has the highest hardware priority is prioritized over the other interrupts.
Previous Version:
When two or more interrupt requests which have the same priority level are sampled active at the time of priority resolution, they are arbitrated in such a way that the first interrupt requested has priority.
* The evaluation MCUs mounted in the products concerned are involved in this previous version. So, if your product is included in the above list, care must be exercised until its evaluation MCU is replaced.
