(RX630, RX63N, RX631, RX210, RX220, X110, RX111) What types of resonator can be connected and what can you recommend?
ceramic resonator or a crystal resonator can be used for the main clock oscillator. Please use a crystal resonator for the sub-clock oscillator. There are no particular resonators that we recommend.

I wish to designate the USP as the stack pointer in supervisor mode.
If the program is for generating interrupts, in addition to setting the USP register you also need to set the ISP register before an exception occurs. When an exception occurs, the processor will automatically switch to supervisor mode (PM bit in PSW register = 0). In addition, while the exception handler ...
