A character precedes a data or address parameter to specify the numeric format, as follows (if
not specified, the format is hexadecimal):
An asterisk (*) following a signal name for signals that are level significant denotes that the
signal is true or valid when the signal is low.
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.
