Channel Configuration
Each channel configuration word consists of bit fields, the settings of which
determine how the channel operates. See this table and the descriptions that
follow for valid configuration settings and their meanings.

(1) An attempt to write any non-valid (spare) bit configuration into any selection field results in a module configuration error.
TIP Default settings for a particular function are indicated by zeros.
For example, the default filter frequency is 60 Hz.
