CRCID
S tar t
The CRCID parameter contains the CRC start value.
Configuring the CRC starting value enables a data
value to be clearly assigned to a slave, as the CRC
check fails with a faulty configuration of the master or
an exchange sequence. For example, the controller
assigns a start value for each slave and writes these
to the CRCID slave parameter.
