In the chaining, the entire "IID_CMD_STRUCT" buffer ("IID_CMD_STRUCT[1...10]") can be
used. The start of the chain is set with the "CMDSEL" parameter.
If several commands are executed in the chain for which data is returned, the position of the
data in the receive buffer "RXREF" can be set for each individual command using the
"IID_CMD_STRUCT[x].OFFSETBUFFER" parameter.
Note
"IID_CMD_STRUCT[1]" reserved for "INIT"
In the Ident profile, the "IID_CMD_STRUCT[1]" parameter is reserved for "INIT". If you want
to use "IID_CMD_STRUCT[1]" for another command, make sure that the reset parameters
are written into this parameter when there is an "INIT".
