After the initial power-up (from 0 V) or in case the VLF bit returns "1" , make sure to initialize all registers, before using the RTC.
Be sure to avoid entering incorrect date and time data, as clock operations are not guaranteed when the data or time data is incorrect.
Any bit marked with "
z
" should be used with a value of "0" after initialization. (Not writable)
Any bit marked with "
•
"
is a RAM bit that can be used to read or write any data.
Any bit marked with' -- 'is Not writable. Read result is unkown.
The above table shows only the user registers. Due to functional reasons, RTC has different registers not mentioned above table which are
programmed by the manufactorer. Please make sure to only access above mentioned user registers.
By read/write to register of No-Function, other finction are not affected.
