■
Outline of operation
● Data are sent from the communication port to external devices.
● Data of [n] bytes are sent from the unit / communication port set by the UNITSEL instruction,
starting with the starting address (word address) of the sent data area specified by [S].
● Data to be sent are set by the user program, in the area starting with [S].
● The processing result is stored in the area specified by [D].
■
Processing
● The slot numbers and communication port numbers specified with UNITSEL instruction are
obtained from the system data register (SD).
● This instruction confirms that the general-purpose communication clear to send flag of a
specified communication port is ON and the general-purpose communication sending flag is
OFF.
● When sending is enabled, sent data is transferred to the send buffer of a communication port
and a request to send is executed.
