Active (Operating)
4-2
If you are using AT commands, a period of time can exist in which
the contents of Active (Operating) and Active (Saved) differ. Once
you issue an AT&W0 (write) command, however, the two storage
areas are identical.
CONTENTS OF Active (Saved) ARE AUTOMATICALLY COPIED
TO Active (Operating) WHEN A SAVE IS COMMANDED VIA THE
DCP, ON A RESET, OR ON POWER-UP.
