ADDR. SECTION
Address 09h to 0Bh and 15h to 1Fh are not used. Reads or
writes to these registers will not affect operation of the
device but should be avoided.
A register can be read by performing a random read at any
address at any time. This returns the contents of that register
location. Additional registers are read by performing a
sequential read. For the RTC registers, the read instruction
latches all clock registers into a buffer, so an update of the
clock does not change the time being read. A sequential
read will not result in the output of data from the memory
array. At the end of a read, the master supplies a stop
condition to end the operation and free the bus. After a read
or write instruction, the address remains at the previous
address +1 so the user can execute a current address read
and continue reading the next register.

Real Time Clock Registers
Addresses [00h to 06h]
RTC REGISTERS (SC, MN, HR,DW, DT, MO, YR)
These registers depict BCD representations of the time. As
such, SC (Seconds, address 00h) and MN (Minutes,
address 01h) range from 0 to 59, HR (Hour, address 02h)
can either be a 12-hour or 24-hour mode, DT (Date, address
03h) is 1 to 31, MO (Month, address 04h) is 1 to 12, YR
(Year, address 06h) is 0 to 99, and DW (Day of the Week,
address 06h) is 0 to 6.
The DW register provides a Day of the Week status and uses
three bits DW2 to DW0 to represent the seven days of the
week. The counter advances in the cycle 0-1-2-3-4-5-6-0-1-
2-… The assignment of a numerical value to a specific day
of the week is arbitrary and may be decided by the system
software designer. The default value is defined as “0”.
