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.
The TEST bit (3Fh bit7) is used by the manufacturer for testing. Be sure to set "0" for this bit when writing.
Be sure to write "0" by initializing before using the clock module. Afterward, be sure to set "0" when writing.
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 wit' -- '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.
Even if it is done Read/Write access as for “No Function”, a function else has no influence.
When not using Week data, It is not necessary for Week register to be initialized.
By read/write to register of No-Function, other functions are not affected.
