The master terminates the Data Byte loading by issuing
a stop condition, which causes the device to begin the
nonvolatile write cycle. As with the byte write operation,
all inputs are disabled until completion of the internal
write cycle. See Figure 9 for the address, acknowledge,
and data transfer sequence.

be sent by the master after sending at least 1 full data
byte plus the subsequent ACK signal. If a stop is
issued in the middle of a data byte, or before 1 full
data byte plus its associated ACK is sent, then the
device will reset itself without performing the write. The
contents of the array will not be effected.

Issue STOP
edge polling can be initiated immediately. To do this,
the master issues a start condition followed by the
Slave Address Byte for a write or read operation. If the
device is still busy with the nonvolatile cycle then no
ACK will be returned. If the device has completed the
write operation, an ACK will be returned and the host
can then proceed with the read or write operation.
Refer to the flow chart in Figure 11.
