Frequency deviation
Note 1: The total error includes all errors except a quantization error, and is defined as a maximum deviation from the idea
Note 2: Conversion time is different in recommended value by power supply voltage.
Note 3: Please use input voltage to AIN input pin in limit of V
Note 4: Analog reference voltage range; ∆V
Note 5: When AD converter is not used, fix the AV

conversion line.
About conversion time, please refer to "Register Configuration" in the section of AD converter.
When voltage or range outside is input, conversion value becomes unsettled and gives affect to other channel
conversion value.
