8/10-bit A/D Converter Control Register 1 (ADC1)

The 8/10-bit A/D converter control register 1 (ADC1) is used to enable and
disable individual functions of the 8/10-bit A/D converter, select an analog input
pin and check the status of the converter.
■ Register Configuration

These bits select an analog input pin.
When A/D conversion is started (AD = 1) by the software (ADC2: EXT = 0), these bits can be modified
simultaneously.

*: The number of analog input pins vary among products. For the number of analog input pins of a
product, refer to its data sheet.
Notes:
• Do not write to ANS[3:0] any value other than those listed in the table above.
• When the ADMV bit is "1", do not modify these bits. Pins not used as analog input pins can be used as general-
purpose I/O ports.
