Data structure of the parameter channel
Structure of the parameter channel
The parameter channel consists of four words. 1. and 2nd word transfer the parameter
number and index as well as the type of job (read or write) The 3rd and 4th word contains
the parameter contents. The parameter contents can be 16-bit values (such as baud rate) or
32-bit values (e.g. CO parameters).
Bit 11 in the 1st word is reserved and is always assigned 0.
