34934C-001: Extension Header Pin Assignments for 4x64
If you are going to create an expanded-row matrix using multiple modules and 
configuration blocks, plan your wiring placement for each configuration block 
carefully, to allow for a daisy-chain interconnection between configuration 
blocks—in addition to any row wiring you may connect to the expansion headers. 
This interconnection is illustrated in “Arranging Multiple 34934A Modules with 
Configuration Blocks” on page 218.
