IRQ Waveforms
The IRQ /FT pin can also be activated in the battery-backed mode. The IRQ /FT goes low if an alarm
occurs and both ABE and AE are set. The ABE and AE bits are cleared during the power-up transition,
however, an alarm generated during power-up sets AF. Therefore, the AF bit can be read after system
power-up to determine if an alarm was generated during the power-up sequence. Figure 4 illustrates alarm
timing during the battery-backup mode and power-up states.
