4.2 Electrical Interface Detail Format
Details of each electrical interface is contained in paragraph 5 (beginning page 19). The
description of each interface follows a common format. An example is shown below:
Interface Name
This is the name of the interface; usually this is the actual name found in the pin list;
sometimes this is a collective name for a number of signals, such as the example
shown here for a UART.
Function:
This identifies the basic function of the interface; some interfaces are grouped
according to their functional sub-class.
Description:
The description contains a basic overview of the interface and its functional
relationship with the host.
Pin Numbers:
All pin numbers associated with the interface are listed; these will not necessarily
be in numerical order but may be arranged to coincide with signal name list.
Signal Names:
All sigal names associated with the interface exactly as shown in the pin list; the
signal names also contain information on signal flow direction.
If not used:
This gives specific details, for each signal, of how to terminate the physical
connection if it is not required by the host; failure to observe this convention may
result in unstable operation of the EDGE modem. (This may not be necessary in the
host application since all signals have a defined function).
