Flow Diagram “Transmit Continuous Command”
Transmit + Receive Same Time Slot Command
The transmit + receive same time slot command can be used to send a message to a
subscriber circuit, which will respond with an answer, e.g. reading back the coefficients
of a SICOFI device. After first transmitting the contents of the MFFIFO (as with the
normal transmit command), the MFFIFO is ready to accept an incoming message which
can then be read by the P when the transfer is completed.
