VL
VL = 0: reliable clock/calendar information is guaranteed;
VL = 1: reliable clock/calendar information is no longer
guaranteed.
6 to 0
<seconds>
These bits represent the current seconds value coded in BCD
format; value = 00 to 59.
Example: <seconds> = 101 1001, represents the value 59 s.

<days>
These bits represent the current day value coded in BCD format;
value = 01 to 31.
The PCF8563 compensates for leap years by adding a 29th day to
February if the year counter contains a value which is exactly
divisible by 4, including the year ‘00’.
