Appendix A.
A.1
Send Checksum Command in TWI Mode
"When a write user zone command is sent in authentication mode or encryption mode the data is saved in a buffer until a
cryptographic checksum is received. The host must send the checksum it has computed immediately after the write user zone
command. If the checksum is valid, CryptoMemory writes the data; if the checksum is incorrect the data is discarded and the
cryptographic engine is reset.
If there is any activity on the TWI bus between the write user zone command and the send checksum command the EEPROM
write may be aborted and the data in the user zone will be unchanged."
