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.
