I was wondering if the act of placing the CY14B101 RTC in calibration mode, upsets the time the device is maintaining. For example, if the RTC is in calibrate mode for x milliseconds, will the RTC still maintain time for those x milliseconds. Or does the RTC lose the time it is in calibration mode?

Thank you

Hi Raymond,

The Calibration process will not affect the time the device is maintaining. Once you determine the calibration required by the device you provide the data in the calibration register and the clock is adjusted thereafter to reflect the changes in the frequency. You can also read our app note on RTC calibration for more information.
