Note: Insert a damping resistor if
required. The resistance will
vary depending on the oscillator
and the oscillation drive
capacity setting. Use the value
recommended by the maker of
the oscillator.
When the oscillation drive
capacity is set to low, check that
oscillation is stable.
Clock Generating Circuit
A ring oscillator is built into the microcomputer. The oscillation of the ring oscillator can be used as the
BCLK by setting the main clock select bit (bit 2 of address 000C). Lower power consumption can be
realized because the oscillating frequency of the ring oscillator is much lower compared to that of XIN. The
frequency of the ring oscillator depends on the supply voltage and the operation temperature range. Be
careful that variable frequencies and obtain the sufficient margin when designing application products.
