S GRAY
Gray/binary data conversion of sensor (required for SSI encoders)
1) _{The length of the data should be given minus 1, i.e. for 64 data bits enter 63.}
2) _{If 0000 0000b is entered as the CRC polynomial, no cyclic redundancy check is carried out. As the last bit of}
a CRC polynomial is always 1 this is not entered in the polynomial register but added in the master. A CRC
polynomial of up to 8 bits is thus possible. Should the full polynomial length not be required, the polynomial
(minus its final 1) must be justified right and the spaces before it filled with zeros. For example, CRC
polynomial 10 0011b is stored as 001 0001b.
