GPIO Open Drain Register (GPODR)
GPIO Data Register (GPDAT)
Direction. Indicates whether a signal is used as an input or an output. Bits D0–D15 correspond to signals
GPIO[0:15]. Bits D16–D31 are unused.
0 The corresponding signal is an input.
1 The corresponding signal is an output.
Open-drain configuration. Indicates whether a signal is actively driven as an output or an open-drain driver.
This register has no effect on signals programmed as inputs in the corresponding GPDIR. Bits D0–D15
correspond to signals GPIO[0:15]. Bits D16–D31 are unused.
0 The I/O signal is actively driven as an output.
1 The I/O signal is an open-drain driver. As an output, the signal is driven active-low, otherwise it is
three-stated.
