REGISTER ACCESS
The contents of the registers can be modified by performing
a byte or a page write operation directly to any register
address.
The registers are divided into 10 sections. They are:
1. Real Time Clock (8 bytes): Address 00h to 07h.
2. Status (2 bytes): Address 08h to 09h.
3. Counter (2 bytes): Address Ah to Bh.
4. Control (9 bytes): 0Ch to 14h.
5. Day Light Saving Time (8 bytes): 15h to 1Ch
6. Alarm 0/1 (12 bytes): 1Dh to 28h
7. Time Stamp for Battery Status (5 bytes): Address 29h to
2Dh.
8. Time Stamp for VDD Status (5 bytes): Address 2Eh to
32h.
9. Time Stamp for Event Status (5 bytes): 33h to 37h.
Write capability is allowable into the RTC registers (00h to
07h) only when the WRTC bit (bit 6 of address 0Ch) is set to
“1”. Other sections do not need to have the WRTC bit set for
write access. A read or write can begin at any address within
the section. A write to sections 2 through 9 can be
continuous. A write can overlap two or more sections as
well.
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 and Alarm registers, the read
instruction latches all clock registers into a buffer, so an
update of the clock does not change the time being read. At
the end of a read, the master supplies a stop condition to
end the operation and free the bus. After a read, the address
remains at the previous address +1 so the user can execute
a current address read and continue reading the next
register.
It is only necessary to set the WRTC bit prior to writing into
the RTC registers. All other registers are completely
accessible without setting the WRTC bit.
