Question:
How important are acknowledgement (malfunction) checks
Answer:
[Why acknowledgement is important]
The I2CBUS protocol includes an acknowledgement check function (for an outline of this function, see
“FAQ Acknowledgement”) as a handshake function to prevent communication errors. This function can
detect improper data communication between a microcomputer and EEPROM.
Due to the specifications of the software, some users may ignore this function and continue to execute a
command. This, however, may result in a malfunction, miswriting, or hang-up. We recommend that
acknowledgement checks be executed from the microcomputer.
