10. Precaution for use
*1. In the S-24C01C, setting W7 is arbitrary.
The S-24C01C/02C does the write operation only when it receives data of 1 byte or more and receives a stop

By a start condition, users are able to cancel command which is being input. However, adjust the phase while the S-
24C01C/02C is outputting “L” because users are not able to input a start condition. When users cancel the command,
there may be a case that the address will not be identified. Use random read for the read operation, not current

Especially, in occasions like picking the S-24C01C/02C up from low temperature tank during the evaluation. Be
sure that not remain frost on the S-24C01C/02C pin to prevent malfunction by short-circuit.
Also attention should be paid in using on environment, which is easy to dew for the same reason.
