INPUT_PULLUP means "internally pull-up open drain"? DA14580's pin mode

Hi,

The port pin's INPUT_PULLUP means "internally pull-up open drain" or not ?
For clarify, The circuit image "pull-up open drain" is shown this -> http://cfile6.uf.tistory.com/original/2249FB42558E3DDF351CD1 (in this image the pullup resistor is external)

If the DA14580 port pin's INPUT_PULLUP is "internally pull- up open drain" , how can I "Drive Low"?
"Drive Low" means the switching to ground in above image.

Hi igotit,

Hi igotit,

There is no open drain circuit in the da's GPIO's.

Thanks MT_dialog
