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. When the previous address is
2Fh, the next address will wrap around to 00h.
It is not necessary to set the WRTC bit prior to writing into the
control and status, alarm, and user SRAM registers.
