AMENDMENT
Élan™SC400 Microcontroller
Register Set Reference Manual
Including Changes for the ÉlanSC410 Microcontroller
This document amends the Élan™SC400 Microcontroller Register Set Reference Manual, order #21032A, including
additional information for the ÉlanSC410 microcontroller. It consists of three parts:
■ “Documentation Defects and Corrections” lists documentation defects found in the original publication.
■ “Changes for the ÉlanSC410 Microcontroller” on page 25 gives an overview of differences between the
ÉlanSC400 microcontroller and the ÉlanSC410 microcontroller, and lists all the registers and bits not supported
on the ÉlanSC410 microcontroller.
■ The Index beginning on page 35 includes all of the registers listed in this document, with index offsets listed sep-
arately by subsystem.
DOCUMENTATION DEFECTS AND CORRECTIONS
Table 1 lists defects that have been found in the
Élan™SC400 Microcontroller Register Set Reference
Manual, order #21032A. Defects are listed in page or-
der. Each entry lists the following:
the original and changed default values are shown for
the whole register. If other text is changed, the entry de-
scribes the affected part of the diagram and lists the
original and changed text.
■ page number
Each item description includes the register name, so
changes affecting a particular register can be found by
consulting the index in this document.
■ item to be corrected
■ original text
Unchanged portions of a paragraph are replaced by an
ellipsis (...) in entries where this might make the
change easier to find. The whole paragraph is included
if it is useful for understanding why the change was
made.
■ corrected text
■ comments explaining the change
Table entries that correct text in a diagram do not con-
tain the entire diagram. If a default value is changed,
