The connection diagrams for the two-supply is shown below.
For two supply configuration, the recommendation is to power all supplies together. If that is not possible then the following power sequencing needs to be used.
|t1||Supply ramp time||Applicable to all supplies||0.5||100||ms|
|t2||Time instance at which VDDIO starts up||Measured with respect to start of VDDA2P5 and VDDA1P1||50||ms|
