(1)
The device continues its operation in Manual mode channel 0 through out 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 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
programming the device continues its operation in whatever mode it is in and outputs valid data.

OPERATING IN MANUAL MODE
The details regarding entering and running in Manual channel sequencing mode are illustrated in Figure 50.
Table 1 lists the Mode Control Register settings for Manual mode in detail. Note that there are no Program
Registers for manual mode.
