Oscillation Stop and Re-oscillation Detect Function
The oscillation stop and re-oscillation detect function is such that main clock oscillation circuit stop and re-
oscillation are detected. At oscillation stop, re-oscillation detection, reset or oscillation stop, re-oscillation
detection interrupt are generated. Which is to be generated can be selected using the CM27 bit of CM2
register. Main clock oscillator of M16C/6S does not stop even if Xin input stops. Oscillation stop re-oscilla-
tion detect circuit does not function.
