6.4.1 Drive Modes
Each GPIO and SIO pin is individually configurable into one of the eight drive modes listed in
used for each pin (DM[2:0]) and set in the PRTxDM[2:0] registers.
drive modes.
selected. Note that the actual I/O pin voltage is determined by a combination of the selected drive mode and the load at the pin. For
example, if a GPIO pin is configured for resistive pull-up mode and driven high while the pin is floating, the voltage measured at the
pin is a high logic state. If the same GPIO pin is externally tied to ground then the voltage unmeasured at the pin is a low logic state.
