... OPERATION The main elements of the DS1603 are shown in Figure 1. As shown, communications to and from the elapsed time counter occur over a 3-wire serial port. The port is activated by driving Note: Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple revisions of any device may be simultaneously available through various sales channels ...

... After the first eight clock cycles have loaded the protocol register with a valid protocol additional clocks will output data for a read or input data for a write. V DS1603 < the DS1603 will switch to internal power and disable the serial port to conserve CC TP energy. When running off of the internal power supply, only the continuous counter will continue to count and the counter powered by V power was lost ...

... Data is driven out the DQ pin as long as CLK is low. When CLK is high the DQ pin is tristated. OSCILLATOR OUTPUT Pin 6 of the DS1603 module is a 1Hz output signal. This signal is present only when V greater than the internal power supply. However, the output is guaranteed to meet TTL requirement only while V is within normal limits ...
