      Operation mode.
      Mode 0  - 7 single-ended voltage readings (IN0-IN6), 1 temperature
      reading (internal).
      Mode 1 - 8 single-ended voltage readings (IN0-IN7), no temperature.
      Mode 2 - 4 pseudo-differential voltage readings
      (IN0-IN1, IN3-IN2, IN4-IN5, IN7-IN6), 1 temperature reading (internal).
      Mode 3 - 4 single-ended voltage readings (IN0-IN3), 2 pseudo-differential
      voltage readings (IN4-IN5, IN7-IN6), 1 temperature reading (internal).
