Detailed Description

GPIO Configuration Mode Elements values convention: 0xX0yz00YZ.

• X : GPIO mode or EXTI Mode
• y : External IT or Event trigger detection
• z : IO configuration on External IT or Event
• Y : Output type (Push Pull or Open Drain)
• Z : IO Direction mode (Input, Output, Alternate or Analog)
