The formula in Fig. 5 is used by software to continually
update the digital trimming register and so compensate
the V3025 for the ambient temperature.
The timer is used to measure the duration the valve is
on.
The alarm feature is used to turn the controller power
on and off at the time programmed by software. The
V3025 pulls IRQ active low on an alarm even in
standby and thus can control the power on/off switch for
the controller.
