Board Level Hardware Description

1-6

General specifications for the MVME166 are listed in Table 1-1.

Throughout this manual, a convention is used which precedes data and 
address parameters by a character identifying the numeric format as follows: 

For example, "12" is the decimal number twelve, and "$12" is the decimal 
number eighteen.  

Unless otherwise specified, all address references are in hexadecimal.  

An asterisk (*) following the signal name for signals which are level significant 
denotes that the signal is true or valid when the signal is low.
