... OE OPERATION—WRITE REGISTERS The DS1386 is in the write mode whenever the WE (Write Enable) and CE (Chip Enable) signals are in the active (Low) state after the address inputs are stable. The latter occurring falling edge will determine the start of the write cycle. The write cycle is terminated by the earlier rising edge ...

... BCD. Registers E through 1FFF or 7FFF are user bytes and can be used to maintain data at the user’s discretion. CLOCK ACCURACY (DIP MODULE) The DS1386 is guaranteed to keep time accuracy to within ±1 minute per month at +25°C. CLOCK ACCURACY (POWERCAP MODULE) The DS1386P and DS9034PCX are each individually tested for accuracy. Once mounted together, the module is guaranteed to keep time accuracy to within ± ...
