OPERATION

The block diagram in Figure 3 shows the main elements of the DS1337. As shown, communications to

and from the DS1337 occur serially over a 2-wire, bidirectional bus. The DS1337 operates as a slave

device on the serial bus. Access is obtained by implementing a START condition and providing a device

identification code, followed by data. Subsequent registers can be accessed sequentially until a STOP

condition is executed.
