GENERAL DESCRIPTION
The DS1678 real-time clock (RTC) event recorder
records the time and date of a nonperiodic,
asynchronous event each time the
INT
pin is
activated. The device records the seconds, minutes,
hours, date, day of the week, month, year, and
century when the first event occurs, and starts the 16-
bit elapsed time counter (ETC). Subsequent events
trigger the recording of the ETC into the event-log
memory. This allows for up to 1025 events to be
logged. Events can be logged while the device is
operating from either V
CC
or V
BAT
.
