Description
1-Wire Reset Pulse generated by master
1-Wire Presence Pulse generated by slave
Command and data to satisfy the ROM function protocol (Skip ROM, Search ROM, etc.)
Command "Write Scratchpad"
Command "Read Scratchpad"
Command "Copy Scratchpad"
Command "Read Memory"
Command "Read Memory with CRC"
Command "Clear Memory"
Command "Convert Temperature"
Target Address TA1, TA2
Target Address TA1, TA2 with E/S byte
Transfer of as many data bytes as are needed to reach the scratchpad offset 1Fh
Transfer of as many data bytes as are needed to reach the end of a memory page
Transfer of as many data bytes as are needed to reach the end of the datalog memory
Transfer of as many 00h bytes as are needed to reach a memory page boundary
Transfer of 32 bytes
Transfer of an undetermined amount of data
Transfer of an inverted CRC16
Indefinite loop where the master reads FFh bytes
Indefinite loop where the master reads AAh bytes
Interval during Copy Scratchpad where the DS1921H/Z does not respond. Any bits read
during this time are logic 1.
Indefinite loop where the master reads 00h bytes
