6.5 DDLM_Chk_Cfg
The configuration function allows the Master to send the
configuration data to the Slave for any check operation. The main
purpose of this function is to define the number of bytes used for the
Data_Exchange as viewed from the Master side.
Chk_Cfg message structure (1 byte):
bit 7 = Consistency (= "1")
bit 6 = Word format ("0" = byte, "1" = word = 4 bytes)
bits 5 - 4 = In/out data ("01" = Input, "10" = Output)
bits 3 ... 0 = Length code
Example

D1hex = 4-byte input
