ALL=impedance
GPIO Pad Control. Each bit in this register configures the pad for the associated GPIO pin in this port.
ALL | The two bits in GPIO_PADCTRL0 and GPIO_PADCTRL1 for each GPIO pin work together to determine the pad mode when the GPIO is set to input mode. 0 (impedance): High Impedance. 1 (pu): Weak pull-up mode. 2 (pd): weak pull-down mode. |
