Note 1: The conversion times are given in cycles of fAD. fAD is derived from f(Xin) divided by 1, 2, 4, or 8
and may not exceed 10 MHz. Minimal conversion times are achieved with an f(Xin) of 10 MHz or 20
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 the VREF is unconnected at the
A-D control register, IVREF is sent.
