Operation
M41T0
2.2
READ Mode
In this mode, the master reads the M41T0 slave after setting the slave address (see
Figure 7). Following the WRITE Mode Control Bit (R/W = 0) and the Acknowledge Bit, the
word 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 M41T0 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 M41T0
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 9 on page 12).
