Hi,

in chapter 1.1.4 of AN4661 is descriped that if DSI is not used at all then:

''The VDDDSI pin must be connected to global VDD''

There is also written:

''The VDDDSI pin must be grounded.''

Is this a typo? What is correct? Both requirements do not make sence together.

Hi neumann.sascha,

Thank you for bringing this feedback to us. Here is a correction for this point:

“

If the DSI functionality is not used at all, then:

• The VDDDSI pin must be connected to global VDD.

• The VCAPDSI pin must be connected externally to VDD12DSI but the external capacitor is no more needed.

• The VSSDSI pin must be grounded.

“

Sorry for the inconvenience.
