VCC = 3V
Table 1.21.22. D-A conversion characteristics (referenced to VCC = AVCC= VREF= 3V, VSS = AVSS =
0V, at Ta = 25oC, f(XIN) = 7MHZ unless otherwise specified)
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.

0V at Ta = 25oC, f(XIN) = 7MHZ, with wait unless otherwise specified)
