Note: Divide the frequency if f(XIN) exceeds 10 MHz, and make ØAD equal to or lower than 10 MHz.

Note: This applies when using one D-A converter, with the D-A register for the unused D-A converter set to “0016”.
The A-D converter's ladder resistance is not included.
Also, when DA register contents are not “00”, the current IVREF always flows even though Vref may
have been set to be “unconnected” by the A-D control register.
