NAME
FUNCTION
Event Input. The EVENT pin controls when the values in the Elapsed Time Counter (ETC) register and
1
EVENT the Event Counter register are incremented. The EVENT pin also determines when the data in these
registers is stored to EEPROM.

met. The active state of this pin is controlled by the ALRM POL bit located in the Configuration register.
Once the ALARM pin is active, it will remain active until the alarm condition is cleared and the CLR
ALM bit in the Command register is set.

GND Ground
5
SCL
I²C Serial-Clock Input. The SCL pin is the serial-clock input for the I²C synchronous communications
channel. The SCL pin is an input that requires an external pull-up resistor.
6
SDA
I²C Serial-Data Input/Output. The SDA pin is the data input/output signal for the I²C synchronous com-
munications channel. The SDA pin is an open-drain I/O, which requires an external pullup resistor.
