Abstract
The hardware of an over-sampling A/D and D/A converter is provided, which hardware is capable of being operated with either kind of software: one corresponding to a first method in which the over-sampling ratio is fixed and the other corresponding to a second method in which the over-sampling ratio is variable. The value N written on the pseudo-frequency-dividing-ratio-register and the value N written on the pseudo-over-sampling-ratio-register are converted through a user interface into the frequency dividing ratio N by the conversion circuit and the converted result is written in the frequency-dividing-ratio-register
