Question:
Method for resetting the S-24 series, phase matching during access: malfunction
Answer:
Method for resetting the EEPROM
The EEPROM can be normally reset using start and stop commands. However, while the EEPROM is
reading data ‘0’ or outputting an acknowledgement signal, ‘0’ is being output to the SDA line so the
microcomputer cannot output a command to the SDA line. In such a case, end the acknowledgement-
signal output operation or read operation of the EEPROM, and enter a start command.
Fig. 1 shows this procedure. First, enter a start condition. Then, send SCL for nine clocks (dummy
clocks). During this operation, the microcomputer keeps the SDA line at a high level. The EEPROM
then aborts the acknowledgement-signal output operation or data output, so enter a start condition. (*2)
This resets the EEPROM. Then, input a stop condition to the EEPROM to ensure safety. Normal
operations will then be enabled.
We recommend that this reset method using dummy clocks be executed following activation of the
power voltage and during system initialization.
