Operation

Characteristics

READ mode
In this mode, the master reads the M41T00AUD slave after setting the slave address (see
Figure 8). Following the WRITE mode control bit (R/W = 0) and the acknowledge bit, the
word (register) address An is written to the on-chip address pointer. Next the START
condition and slave address are repeated, followed by the READ mode control bit (R/W = 1).
At this point, the master transmitter becomes the master receiver. The data byte which was
addressed will be transmitted and the master receiver will send an acknowledge bit to the
slave transmitter. The address pointer is only incremented on reception of an acknowledge
bit. The device slave transmitter will now place the data byte at address An+1 on the bus.
The master receiver reads and acknowledges the new byte and the address pointer is
incremented to An+2.
This cycle of reading consecutive addresses will continue until the master receiver sends a
STOP condition to the slave transmitter.
An alternate READ mode may also be implemented, whereby the master reads the
M41T00AUD slave without first writing to the (volatile) address pointer. The first address
that is read is the last one stored in the pointer (see Figure 10).
