Interrupt output
The conditions for activating the open-drain n-channel
interrupt output INT (active LOW) are determined by
appropriate programming of the alarm control register.
These conditions are clock alarm, timer alarm, timer
overflow, and event counter alarm. An interrupt occurs
when the alarm flag or the timer flag is set, and the
corresponding interrupt is enabled. In all events, the
interrupt is cleared only by software resetting of the flag
which initiated the interrupt.
In the clock mode, if the alarm enable is not activated
(alarm enable bit of control/status register is logic 0), the
interrupt output toggles at 1 Hz with a 50% duty cycle (may
be used for calibration). The OFF voltage of the interrupt
output may exceed the supply voltage, up to a maximum
of 6.0 V. A logic diagram of the interrupt output is shown in
Fig.11.
