2.3 Operating Mode Monitoring
The levels on the operating mode setting pins can be confirmed by using the operating mode monitoring register.
The table below lists the operating mode setting pins for which the settings can be checked.
For details of the operating mode monitor register, refer to the R-IN32M3 Series User's Manual (Peripheral Modules).

2.4 Buffer Switching
The driving ability and use of a pull-up or pull-down resistor is programmable for real-time and general-purpose port
pins (with some exceptions).
The former function provides stable operation in systems with large loads by providing the ability to raise the driving
ability.
Use the buffer-switching registers (DRCTL) to change the output buffers as required.
For details of the buffer switching registers, refer to the R-IN32M3 Series User's Manual (Peripheral Modules).
