GPIO Set Pin State
GPIO Falling Edge
GPIO Rising Edge
GPIO Pull Down
Register Name
GPIO Pull Up
Reading this bit yields the current state of the bit. Writing has no
effect.
Writing ‘1’ to this bit causes the corresponding GPIO to go to ‘1’
state. Writing ‘0’ has no effect.
Writing ‘1’ to this bit causes the corresponding GPIO to go to ‘0’
state. Writing ‘0’ has no effect.
‘0’ sets the corresponding GPIO to input state, and ‘1’ sets it to
output state
Set to ‘1’ by hardware when there is a rising/falling edge on the
corresponding GPIO. Writing ‘1’ clears the bit. Writing ‘0’ has no
effect.
Set to ‘1’ to enable rising edge detection on the corresponding
GPIO.
Set to ‘1’ to enable falling edge detection on the corresponding
GPIO.
Set to ‘1’ to enable internal pull-up resistor
Set to ‘1’ to enable internal pull-down resistor
