M41T256Y

Operating modes

13/30

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 8 on page 14).

Note:

Address pointer will wrap around from maximum address to minimum address if

consecutive READ or WRITE cycles are performed.

An alternate READ mode may also be implemented whereby the master reads the

M41T256Y 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 14).
