FALSE, Toggle bit for transmitting new orders from the
TRUE application to the module. If TGL_SM and TGL_MS
have the same status, a new order has not yet been
initiated. If the flags have different statuses, a new order
has been initiated and is currently being processed.
FALSE Parameter data are being read from A7 ... A0
TRUE Parameter data are being written to A7 ... A0

respective order is being processed by the module. If both
flags have the same status, then the order for the
previously sent or requested parameter has been
completed.
FALSE The transmission of the parameters has been completed in
the agreed time (parameter address 0).
