|port||I/O port number (0 to 255)|
This command sets the port's I/O mode to output and outputs logic low or 0V (GND).
Output 8 'Set port 8's I/O mode to output LOW 8
When a port is set to logic high, the port is internally connected to VDD (5V). If it is set to a logic low, the port is internally connected to VSS (0V). This allows either source or sink interfacing to external components (up to 25mA for source or sink).
