Table 104. Boundary-scan Signals for the ADC (Continued)
Note:
If the ADC is not to be used during scan, the recommended input values from
be used. The user is recommended not to use the Differential Gain stages during scan. Switch-
Cap based gain stages require fast operation and accurate timing which is difficult to obtain
when used in a scan chain. Details concerning operations of the differential gain stage is there-
fore not provided.
