CRC
(6 bits)
Correct transmission control (inverted output). Cyclic Redundancy Check is an
error checking which is the result of a “Redundancy Checking” calculation
performed on the message contents. This is intended to check whether
transmission has been performed properly. It is 6-bit long.

6.4 Control Data CD
Main control data is described in this section. Please refer to the official BiSS
documents for complete CD structure: “BiSS C Protocol Description” in the BiSS
homepage.
Register address
It sets the number of the register you need either to read or to write. It is 7-bit
long.
RW
RW
= “01”: when you need to write in the register.
= “10”: when you need to read in the register.
It is 2-bit long.
DATA
When you need to write in a register (
= “01”), it allows to set the value to
be written in the register (transmitted by the Master to the Slave).
When you need to read in a register (
= “10”), it shows the value read in the
register (transmitted by the Slave to the Master).
It is 8-bit long.
