Control data
*1 This is the maximum setting range in a multiple CPU system consisting of two CPU modules.
It may be less than 8192 because the number of data points that can be read varies depending on the system configuration. (
1401 Another CPU Module Access Instructions)
Processing details
• In a multiple CPU system, these instructions read the data in the device specified by (d1) in the host CPU module, by the
number of read data points specified by (s1)+1, and store it in the device specified by (d1) and later in another CPU module
(U/H).
• The following figure shows an outline of operation of the D(P).DDRD and M(P).DDRD instructions.
