Bit Field Type Reset Description
31-30 SCHEME RO 0h
Used to distinguish between old scheme and current.
0h = (Read): Legacy ASP or WTBU scheme
1h = (Read): Highlander 0.8 scheme
29-28 RESERVED R X
27-16 FUNC RO 0h
Function indicates a software compatible module family. If there is
no level of software compatibility, a new Func number (and hence
REVISION) should be assigned.
15-11 R_RTL RO 0h
RTL Version (R), maintained by IP design owner.
RTL follows a numbering such as X.Y.R.Z which are explained in
this table.
R changes ONLY when:
(1) PDS uploads occur which may have been due to spec changes
(2) Bug fixes occur
(3) Resets to 0 when X or Y changes.
Design team has an internal Z (customer-invisible) number which
increments on every drop that happens due to DV and RTL updates.
Z resets to 0 when R increments.
10-8 X_MAJOR RO 0h
Major Revision (X), maintained by IP specification owner.
X changes ONLY when:
(1) There is a major feature addition. An example would be adding
master mode to Utopia Level2. The Func field (or class/type in old
PID format) remains the same.
X does NOT change due to:
(1) Bug fixes
(2) Change in feature parameters.
7-6 CUSTOM RO 0h
Indicates a special version for a particular device. Consequence of
use may avoid use of standard Chip Support Library (CSL) / Drivers.
0h = (Read): Non-custom (standard) revision
