CRC GENERATION
To validate the data transmitted from the DS2405, the bus master may generate a CRC value from the
data as it is received. This generated value is compared to the value stored in the last 8 bits of the
DS2405. If the two CRC values match, the transmission is error-free.
The equivalent polynomial function of this CRC is:
CRC = x8 + x5 + x4 + 1
For more details, see the Book of DS19xx iButton Standards.
