18. CLRC663 Command set
18.1 General description
The behavior is determined by a state machine capable to perform a certain set of
commands. By writing the according command-code to register Command_Reg the
command is executed.
Arguments and/or data necessary to process a command, are exchanged via the FiFo
buffer.
18.2 General behavior
A data transmission of the TxEncoder can be started by a command. When started,
the communication is executed as defined in the TxFrameCon register. Therefore a
communication frame can consist of a start-symbol, a data-stream, and followed by
an end-symbol.
Each command that needs a certain number of arguments will start processing only
when it has received the correct number of arguments via the FiFo buffer.
The FiFo buffer is not cleared automatically at command start. Therefore, it is also
possible to write the command arguments and/or the data bytes into the FiFo buffer
and start the command afterwards.
Each command may be interrupted by the host by writing a new command code into
register Command_Reg e.g.: the Idle-Command.
