1:Customers TTI using PCF85063AT have 6S offset a day.
If mode 0 ,calculate the offset register value is +2(calculation 8.686ppm/4.34).
How can i write register address 0x02? Write 0x02(+2 offset value ) in address 0x02 or Write 0x7E(-2 offset value ) in address 0x02 to calibration offset ?
Could you provdie the PCF85063AT driver code to TTI reference。How to de-offset calibration.
2: The PCF85063AT internal integration a 32.768Khz OSCILLATOR. Is it possible to omit the external 32.768Khz quartz?

1:
For example, if you calculate Offset=+3, you will enter +3 in Offset register; and RTC will apply correction equal to -3.
For example, if you calculate Offset=-5, you will enter -5 in Offset register; and RTC will apply correction equal to +5.
2:No,it isn't .
