Cautions 1. When writing data to the ADA0S register in the following modes, stop the A/D
conversion by clearing the AD0M0.ADA0CE bit to 0. After the data is written to the
register, enable the A/D conversion again by setting the ADA0CE bit to 1.
• Normal conversion mode
• One-shot select mode/one-shot scan mode in high-speed conversion mode
2. Be sure to clear bits 7 to 4 to “0”.
