Example: PIC with EM203

Below is an annotated schematic, showing how one would go about connecting an EM203A device to a PIC (Programmable Interrupt Controller -- a type of common controller chip). The PIC is used merely as an example -- the information below applies to any similar connection.


Note that the pins shown below are not all of the pins an EM203A has. There are other pins, which are not used in this example.
