If a pin is configured as "High Impedance Digital", as an input, there should be

   

a caution about the pin potentially drawing input current if left floating.

   

 

   

If this is true docs to be affected, TRM, AN72382, AN60580, AN77900.

   

 

   

Bob, who is the contact inside Cypress to handle this ?

   

 

   

Regards, Dana.

Drawing current from Vddd > PMOS out transistor > NMOS out transistor > VSSD.
