  • Page 25: Frequency Characteristics

    5.4. Frequency Characteristics The monitor program only operates at 38600bps. The monitor program operates in developer tool-dedicated high-speed on-chip oscillator. However, note that operation may not be possible when dividing the main clock and using it with less than 1 MHz even in the range of the above frequency. Do not use the low-speed on-chip oscillator clock as the system clock.
