SQW
Square-Wave Output. This signal functions identical to the
DS1689/DS1693 with an exception occurring at power-up. A
32kHz square wave is output on this pin, tREC, after a power-up
condition has been detected. This condition sets the following
bits, enabling the 32kHz output: DV1 = 1, SQWE = 1, and E32K
= 1. The square wave is output on this pin if either SQWE = 1 or
E32K = 1.
