* 1 : When performing write during RUN of the CPU module, set write during RUN setting to "Enable".
* 2 : Set the number of processing points within the range of the following expression.
(Number of word access points)
•One point of a bit device corresponds to 16 bits for word access or to 32 bits for double word
access.
•One point of a word device corresponds to one word for word access or to two words for double
word access.
