READ mode
In this mode the master reads the M41T00CAP 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 clock. The
M41T00CAP 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.
The system-to-user transfer of clock data will be halted whenever the address being read is
a clock address (00h to 06h). The updating will resume upon a stop condition or when the
pointer increments to any non-clock address (07h).
Note:
This is true both in READ mode and WRITE mode.
