Motorola MVME2100 Installation And Use Manual page 19

An asterisk (*) following a signal name for signals that 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.
Data and address sizes are defined as follows:
Byte 8 bits, numbered 0 through 7, with bit 0 being the least significant.
Half word 16 bits, numbered 0 through 15, with bit 0 being the least significant.
Word 32 bits, numbered 0 through 31, with bit 0 being the least significant.
Double word 64 bits, numbered 0 through 63, with bit 0 being the least significant.
