The input threshold voltage of P1.6/SCL and P1.7/SDA meet the I
2
C-bus specification. Therefore, an input voltage
below 0.3V
DD
will be recognized as a logic 0 and an input voltage above 0.7V
DD
will be recognized as a logic 1.

26 ADC CHARACTERISTICS
Notes
1.
2.
3.
All ADC inputs require an external divide-by-2 voltage divider.
Gain error: the maximum difference between actual and ideal slope.
Zero-offset error: the difference between the actual and ideal input voltage corresponding to the first actual code
transition.
Differential non-linearity: the difference between the actual and ideal code widths.
Integral non-linearity: maximum deviation from straight line.
Channel-to-channel matching: the difference between corresponding code transitions of actual characteristics taken
from different channels under the same temperature, voltage and frequency conditions. Not tested, but verified on
sampling basis.
