Note 1: Maximum operating frequency is dependent on the MCU.
Note 2: Software break numbers are dependent on the address match circuit numbers
are built-in MCU.
Note 3: When operating in 3.3V, supply power from the target board. In this case, it is not
possible to change the FoUSB firmware. When the model name of the
microcomputer to be used is changed, remove the target board, supply the USB
bus-powered and rewrite the firmware.
