Clock operation
Write timing
2
When writing to the device, the data is shifted into the M41T62's I
C interface on the rising
edge of the SCL signal. As shown in
Figure
20, on the 8th clock cycle, the data is
2
transferred from the I
C block into whichever register is being pointed to by the address
pointer (not shown).
Writes to the clock registers (addresses 0-7)
Data written to the clock registers (addresses 0-7) is held in the buffer registers until the
2
address pointer increments to 8, or an I
C stop condition occurs, at which time the data in
the buffer/registers is simultaneously copied into the counters, and then the clock is re-
started.
