GPIO Mode 1—
ten to the Port x Data register (Px_DR) is presented on the pin.
GPIO Mode 2—
tristated (high impedance). The value stored in the Port x Data register produces no effect.
As in all modes, a read from the Port x Data register returns the pin’s value. GPIO Mode 2
is the default operating mode following a RESET.
GPIO Mode 3—
ture an internal pull-up to the supply voltage. To employ the GPIO pin in open-drain
mode, an external pull-up resistor must connect the pin to the supply voltage. Writing a 0
to the Port x Data register outputs a Low at the pin. Writing a 1 to the Port x Data register
results in high-impedance output.
GPIO Mode 4—
ture an internal pull-down to the supply ground. To employ the GPIO pin in open-source
mode, an external pull-down resistor must connect the pin to the supply ground. Writing a
1 to the Port x Data register outputs a High at the pin. Writing a 0 to the Port x Data regis-
ter results in a high-impedance output.
