Moved the Typical Operating Circuit and Pin Configurations to first page.
1
Removed the leaded part numbers from the Ordering Information table.
1
Added an open-drain transistor to SQW/OUT in the block diagram (Figure 1).
4
Added the pullup voltage range for SDA, SCL, and SQW/OUT to the Pin
Description table and noted that SQW/OUT can be left open if not used.
6
Added default time and date values on first application of power to the Clock
and Calendar section and deleted the note that initial power-on state is not
defined.
8
Added default on initial application of power to bit info in the Control Register
section.
9
Updated the Package Information section to reflect new package outline
drawing numbers.
