GPO2 may be configured as open-drain or push-pull output. The supply for the push-pull driver is internally connected to the IN_LS1 input pin, whereas an external pullup resistor and supply are required in the open-drain configuration. Because of the internal connection to IN_LS1, the external pullup supply must not exceed the voltage on the IN_LS1 pin, otherwise leakage current may be observed from GPO2 to IN_LS1 as shown in Figure 5-22.
When configured as open-drain output, the external pullup supply must not exceed the voltage level on IN_LS1 pin.
