Port A–C Output Control Subregisters
The Port A–C Output Control subregisters
Control registers by writing
Port A–C Output Control subregisters to 1 configures the specified port pins for open-
drain operation. These subregisters affect the pins directly, as a result, alternate functions
are also affected.
