valid conversion results. It is possible to change channel, range, GPIO by inserting extra frames in between two

programming blocks. It is also possible to bypass any programming block if the user does not intent to use that

feature.

(2) It is possible to reprogram the device at any time during operation, regardless of what mode the device is in. During
