Manual Terminology
Throughout this manual, a convention is used which precedes data and
address parameters by a character identifying the numeric format as follows:
$ dollar specifies a hexadecimal character
% percent specifies a binary number
& ampersand specifies a decimal number
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.
An asterisk (*) following the signal name for signals which are edge-significant
denotes that the actions initiated by that signal occur on high-to-low
transition.
In this manual, assertion and negation are used to specify forcing a signal to a
particular state. In particular, assertion and assert refer to a signal that is active
or true; negation and negate indicate a signal that is inactive or false. These
terms are used independently of the voltage level (high or low) that they
represent.
In this manual, MVME712 series transition module refers generically to the
MVME712-12, MVME712-13, MVME712A, MVME712AM, or MVME712M.
MVME712x transition module refers to the closely related MVME712-12,
MVME712-13, MVME712A, or MVME712AM (not to the MVME712M).
References to a specific module use the complete designation of that module.
Data and address sizes are defined as follows:
❏
A byte is eight bits, numbered 0 through 7, with bit 0 being the least
significant.
❏
A word is 16 bits, numbered 0 through 15, with bit 0 being the least
significant.
❏
A longword is 32 bits, numbered 0 through 31, with bit 0 being the least
significant.
