(5) CR oscillation frequency adjusting control
When OSC1 and OSC3 respectively are set for a CR oscillation circuit and a CR/ceramic oscillation
circuit by a mask option, this control allows you to adjust the oscillation frequency. The oscillation
frequency can be adjusted in the range of approx. 20 kHz to 500 kHz for OSC1 and approx. 100 kHz to
8 MHz for OSC3. Note that the actual IC does not operate with all of these frequencies; consult the
technical manual for the S1C63404/454/455/458/466/P466 to select the appropriate operating
frequency.

OSC1 fine adjustment
OSC3 rough adjustment

(6) CR oscillation frequency monitor pins
These pins allow you to monitor the clock waveform from the CR oscillation circuit with an oscillo-
scope. Note that these pins always output a signal waveform whether or not the oscillation circuit is
operating.
