Figure 13. CRC-16 Hardware Description and Polynomial
by the bus master. The DS2431 transmits this CRC only
if E[2:0] = 111b.
With the Read Scratchpad command, the CRC is gen-
erated by first clearing the CRC generator and then
shifting in the command code, the target addresses
TA1 and TA2, the E/S byte, and the scratchpad data as
they were sent by the DS2431. The DS2431 transmits
this CRC only if the reading continues through the end
of the scratchpad. For more information on generating
CRC values, refer to Application Note 27.

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 data 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.
