An interrupt is generated if the coin cell voltage drops too low (and the main battery is not present). If this interrupt occurs, the RTC might be corrupted. A different interrupt is generated if the crystal oscillator stops; this signifies that handset timing is no longer accurate. Again, the RTC is corrupted.

When the VBAT power supply of the MC509 is normal, the coin cell charging is powered from VBAT. The MC509 reads the coin cell voltage and monitors the charging. During normal operation, the VCOIN pin voltage will stay above 2.2V, even when the coin cell charger is turned off. Figure 3-2shows the reference RTC circuit.
