Hi,

 

I found the difference of schematics between Data Sheet (Fig.4 and 5) and Application note AN11590 (Fig.2 and 3).

Could you tell me which schematics is a correct reference?

 

In the Data Sheet, SWOUT is not connecting to 0.1uF PGND by capacitor (so PVDD33 is connecting to PGND by 0.1uF capacitor) as below.

In AN11590, SWOUT is connecting to PGND by 0.1uF capacitor as below.

 

Best regards,

M.Kiniwa
