Note: Default settings for a particular function are indicated by zero(s). For example,
the default filter frequency is 10 Hz.

4.2.3 Enabling or Disabling a Channel (Bit 15)

You can enable or disable each of the six channels individually using bit 15. The module
only scans enabled channels. Enabling a channel forces it to be recalibrated before it
measures input data. Disabling a channel sets the channel data word to zero.
