User’s Manual Pub. 0300241-01 Rev. A
Each channel configuration word consists of bit fields, the settings of which determine
how the channel operates. See the table below and the descriptions that follow for valid
configuration settings and their meanings.

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.
