[Setting data]
Setting data Description Data type of result
(D)
The CPU shared memory address of self CPU of
the writing destination device. (800H to FFFH)
—
(S)
Start device No. which writing data are stored.
(n)
Number of words to be written (1 to 256)
(D1)
Self CPU device is made to turn on by the writing
completion.
[Functions]
(1) A part for (n)words of data since the device specified with (S) of the self CPU
module are written to since the CPU shared memory address specified with (D) of
the self CPU module. After writing completion of the device data, the complete bit
device specified with (D1) turns on.

(2) Do resetting of the complete bit device by the user program.
(3) Another MULTW instruction cannot be processed until MULTW instruction is
executed and a complete bit device is turned on. When MULTW instruction is
executed again, before MULTW instruction is executed and complete bit device is
turned on, the MULTW instruction executed later becomes an error.
