Functional Description

This LED output can drive any general purpose LED with up to 10mA of current.

 

Hardware Interface: The PSoC pin sources current to a LED or sinks current from a LED through a current limiting resistor based on the property selected by user.

 

Software Interface: The LED state is controlled with an 8-bit unsigned byte. 0 = Off, 1 = On.
