VHSI port specifications

The standards compliant with each interface supported on the VHSI
port are listed in Table 1. The rest of this section describes the pin-outs
that are used to implement the electrical and signaling requirements of
each interface. A wiring diagram is also provided for each interface that
describes how interface pinouts are mapped to the VHSI port.
