Update Menu - Centsys Lattice Installation Manual

4. Update Menu

The fourth main menu item is the "UPd" (update) menu. This menu provides the ability to update
parameters on existing tags. This menu would be used where, say, the APB levels needed to be changed
on an existing tag, or range of tags. It is possible to update in one of the following ways:
By ALL - (i.e. changes are made globally to all tags in the system)
By Id - (i.e. where the tag is not actually available for updating physically, but where the tag or
series of tags belonging to a specific group, or ID number, is known.)
By tAg - (i.e. where the specific tag or tags are physically available for the changes to be made)
By Hd - (This is where changes can be made to tags which pertain to a specific head). This is
further broken down so that updates can be done by:
Hd - (i.e. changes are made to all tags pertaining to a specific head.
Id - (i.e. where the tag is not actually available for updating physically. In this case the user
is presented with only the list of tags that exist for this head. Other tags may be valid for
other heads, but will not be shown.
tAg - (i.e. where the tag update will be for this specific head only)
The update mechanisms are described fully below referring to the Update menu structure (shown in
Figures 29, 30, 31 and 32)
