The detailed explanation of the buffer memory in Section 3.4.4 and later is based on
the 8-channel analog input (CH1 to CH8) of the Q68ADV and Q68ADI.
This section describes the assignment of the Q64AD buffer memory.
POINT
Do not write data from System area or sequence program to the buffer memory
area where writing is disabled. Doing so may cause malfunction.
