DETAILED DESCRIPTION (continued)
NOTES:
1. The device continues its operation in manual mode channel 0 throughout the programming sequence and outputs 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 intend 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
programming the device continues its operation in whatever mode it is in and outputs valid data.
