The parameterization message from the master to the interface module is structured as
follows:

Time base for watchdog = 1 ms
* The time base for the watchdog time is specified as 10 ms in octets 2 and 3. Nothing lower than the digit "2" should ever
be entered in one octet and nothing lower than the digit "1" in the other, in order to ensure that the watchdog time does not
elapse too quickly. A time base of 1 ms is specified in the user parameters of some ASICs due to the 12 Mbaud technology.
** 11 Tbits minimum are specified as standard. This value must be less than the maximum TSDR.
*** The structure of the parameterization message is partly specified as is the case with ASICs LSPM2/SPM2. The SPC3
evaluates the first 7 (without user_prm_data) or the first 8 (with user_prm_data) data bytes. The first seven bytes are defined in
accordance with the standard. The eighth byte is used for SPC3-specific properties and the other bytes are available for the
application.
Response from slave
The slave responds to a parameterization message with "E5H" (short acknowledge). The slave does not
report parameterization errors until later when it receives a diagnostic request from the master.
