Note 1 If the Read Start Address is outside of the variable area, the returned read data will all be 0,
but the specified number of elements will be returned and the processing will end in "normal
completion."
2 If the Read Start Address is within the variable area and the Read End Address (Read Start
Address + Number of Elements) is beyond the last variable area address, the read operation
will be performed as long as the amount of data up to the last variable area address is within
the specified range of the number of elements. The read data beyond the end of the variable
area will all be set to 0. (See the following example.)
