DESCRIPTION
1-Wire reset pulse generated by master
1-Wire presence pulse generated by slave
Command and data to satisfy the ROM function protocol
Command: “Write Scratchpad”
Command: “Read Scratchpad”
Command: “Copy Scratchpad”
Command: “Read Memory”
Target Address TA1, TA2
Target Address TA1, TA2 with E/S byte
Transfer of as many bytes as needed to reach the end of the scratchpad for a given target address
Transfer of as many bytes as are needed to reach the end of the memory
Transfer of an inverted CRC-16
Indefinite loop where the master reads FF bytes
Indefinite loop where the master reads AA bytes
Data transfer to EEPROM; no activity on the 1-Wire bus permitted during this time
