Reading device data from another CPU module
D(P).DDRD, M(P).DDRD
• D(P).DDRD
• M(P).DDRD
These instructions read device data from another CPU module in a multiple CPU system.
■Execution condition
Setting data
■Description, range, data type
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
The RnENCPU with firmware version "25" or later supports these instructions. (Use an engineering tool with version "1.032J" or later.)
