Schematics are included for each library if the implementation differs.
Design elements with bused or multiple I/O pins (2-, 4-, 8-, 16-bit versions) typically include just one schematic - generally the 8-bit version. When only one schematic is included, implementation of the smaller and larger elements differs only in the number of sections. In cases where an 8-bit version is very large, an appropriate smaller element serves as the schematic example.
