PROGRAM OPERATIONS

Sector Programming

The sector program mode requires issuing the 8-bit write

command followed by the password, password Ack

command, the address and then the data bytes trans-

ferred as illustrated in figure 4. Up to 32 bytes may be

transferred. After the last byte to be transferred is

acknowledged a stop condition is issued which starts the

nonvolatile write cycle.
