Background

Some RX MCU peripherals use only fixed interrupt vectors, while some others also use software configurable interrupt vectors.
The software configurable interrupt vectors can configure select which interrupt is enabled by the user depending on the application.
The software configurable interrupt is separated into two types for each clock source (PCKLA and PCLKB) as INTA and INTB.

This is an example of how to remove the error for the GTCIU2 setting in GPT:

 
To resolve this error, you must configure additional interrupt settings in the "Interrupt Interrupts tab".
As shown in the figure below, you need to select the interrupt from the corresponding interrupt vector group, INTA or INTB.

How to verify that the software configurable interrupt is applied

Please check the r_bsp_interrupt_config.h in src/smc_gen/r_config/.
