• SC682-06
An error occurred during EEPROM communication, but recovery failed after retrying three
times.
This SC is detected when there is:
• arbitration loss (AL=1)
• path error (BER=1)
• ACT error
• SC682-11
An error occurred during EEPROM communication, but recovery failed after retrying three
times.
This SC is detected when there is no ACK after sending the slave address (FBT=1 & RACK=1).
• SC682-16
An error occurred during EEPROM communication, but recovery failed after retrying three
times.
This SC is detected when:
• there is no ACK after sending the slave address with the master set to write and RACK for
the register of SSR/IBSR set to 1 (RACK=1).
• stop conditions cannot be detected (SPC=1).
• SC682-21
An error occurred during EEPROM communication, but recovery failed after retrying three
times.
This SC is detected when there was a time-out pending interruption (start conditions are not
issued).
• SC682-26
An error occurred during EEPROM communication, but recovery failed after retrying three
times.

• there is an overrun error (ORE=1).
• there are other errors defined by the software engineer.
