9.1.4. Push-Pull Output
The push-pull output configuration has the same pull-down structure as both the open-drain and the quasi-
bidirectional output modes, but provides a continuous strong pull-up when the port register contains a logic “1”.
The push-pull mode may be used when more source current is needed from a port output. In addition, the input
path of the port pin in this configuration is also the same as quasi-bidirectional mode.
9.2. Maximum Ratings for Port Outputs
While port pins function as outputs (which can source or sink a current), to prevent the device from being
permanently damaged, users should take care the total current not more than 40mA for sourcing or sinking
regardless of a 3.3V device or a 5V device. That means that the device can source total 40mA and sink total
40mA at the same time without causing any damage to it self.
