Notes 1.
If an inrush current flows to one analog input pin (ANIn: n = 0 to 7), the A/D conversion result of the analog
input pin is the value when the inrush current does not flow
±
2 LSB.
2.
If an inrush current flows to two or more analog input pins (ANIn: n = 0 to 7), the A/D conversion result of
the analog input pin is the value when the inrush current does not flow
±
4 LSB.
Remarks 1.
The mean value (absolute value) of the inrush current of a pin can be calculated by the following
expression:
Mean value = ((1/T)
∫

| i (t) |

where i (t) is a pin inrush current, and the maximum value of |i (t)| is the peak value.
