M41ST85W

READ Mode
In this mode the master reads the M41ST85W
slave after setting the slave address (see
Figure
11.
). 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 re-
peated followed by the READ Mode Control Bit (R/
W=1). At this point the master transmitter be-
comes the master receiver.
The data byte which was addressed will be trans-
mitted and the master receiver will send an Ac-
knowledge Bit to the slave transmitter. The
address pointer is only incremented on reception
of an Acknowledge Clock. The M41ST85W 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 (see
Figure
12., page 11
).
The system-to-user transfer of clock data will be
halted whenever the address being read is a clock
address (00h to 07h). The update will resume ei-
ther due to a Stop Condition or when the pointer
increments to a non-clock or RAM address.
Note:
This is true both in READ Mode and WRITE
Mode.
An alternate READ Mode may also be implement-
ed whereby the master reads the M41ST85W
slave without first writing to the (volatile) address
pointer. The first address that is read is the last
one
stored
in
the
