This feature (oversampling) is set in block transfer word 40. This

word specifies the number of times a channel will be sampled and

the results averaged. Legal values of the number of oversamples are:

0, 1, 2, 4, 8, 16, 32, 64, 128, and 256. The format of the data in

this field can be BCD or binary.

If 0 oversamples are chosen, or the block transfer write length is

less than 40, the oversample selection will default to 8.

Block transfer write word 41 is the channel sampling disable word. If

you do not want to include a channel in your sample, set the

corresponding bit to 1, and the channel will NOT be sampled. (In

differential mode, channels 9 through 16 are ignored.) If the

channels are not set (0), or the block transfer write length is less

than 41, all channels will be sampled.

A disabled channel will return 0 in the block transfer read.
