PROGRAM OPERATIONS

Sector Programming

The sector program mode requires issuing the 8-bit write

command followed by the password, password Ack com-

mand, the address and then the data bytes transferred

as illustrated in figure 4. Up to 64 bytes may be trans-

ferred. After the last byte to be transferred is acknowl-

edged a stop condition is issued which starts the

nonvolatile write cycle.
