Illegal command codes will be disregarded. The part will respond with a “no-ACK” to the illegal byte and then return to
the standby mode. All write/read operations require a password.

Sector Write
The sector write mode requires issuing the 8-bit write
command followed by the password and then the data
bytes transferred as illustrated in figure 4. The write com-
mand byte contains the address of the sector to be writ-
ten. Data is written starting at the first address of a sector
and eight bytes must be transferred. After the last byte to
be transferred is acknowledged a stop condition is issued
which starts the nonvolatile write cycle. If more or less
than 8 bytes are transferred, the data in the sector
remains unchanged.
ACK Polling
Once a stop condition is issued to indicate the end of the
host’s write sequence, the X76F102 initiates the internal
nonvolatile write cycle. In order to take advantage of the
typical 5ms write cycle, ACK polling can begin immedi-
ately. This involves issuing the start condition followed by
