NOTES:
5. IRQ and FOUT Inactive.
6. LPMODE = 0 (default).
7. In order to ensure proper timekeeping, the VDD SR- specification must be followed.
8. Typical values are for T = +25°C and 3.3V supply voltage.
9. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
10. Parameter is not 100% tested.
11. These are I2C specific parameters and are not tested, however, they are used to set conditions for testing devices to validate specification.
