Cautions

1. When the injection current has run into the analog input pin (ANn: n = 0-7), the A/D conversion

result of the analog input contiguous to the current injection pin has the value of the standard

in which the injection current is not running plus

±2LSB.

2. The mean value (absolute value) of the pin injected current is as follows:

Mean value = ((1/T)

| i(t) | 3/2dt)2/3

In this, i(t) refers to the pin injected current. The maximum value of |i(t)| is the peak value.
