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".
Command "Extended 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 data bytes as are needed to reach the end of the memory.
Transfer of as many data bytes as are needed to reach the end of the page for a given
target address.
Transfer of an inverted CRC16.
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.
