I am using PCF85263A RTC chipset in my product.
It gets faster every day. So, I want to adjust offset register. (24h Offset OFFSET[7:0])
I don't under stand 2 point.
1. I want to slow RTC . Now RTC get faster every day. Then adding or subtracting clock ?
The correction is made by adding or subtracting clock correction pulses, thereby changing
the period of a single second but not by changing the oscillator frequency.
2. , Would you explain more about below? once every four hours ? once per minute ?
Correction when OFFM = 0
The correction is triggered once every four hours and then correction pulses are applied
once per minute until the programmed correction values have been implemented
