3.1 Edge Connector Interface
The Edge Connector Interface is made up of a male 96 pin DIN of which 64 pins are
actually used. It consists of signals appropriate to read and write to the registers of
the devices on the daughterboard, and it provides the necessary power and ground.
The connections have been specially designed to mate with PMC's PM1501 EVMB
evaluation motherboard. TTL signal levels are used on this interface.
