List of buffer memory addresses

The following table lists the buffer memory addresses of the flexible high-speed I/O control module. For details on the buffer
memory areas, refer to the following.
Page 237 Details of buffer memory areas
The buffer memory areas of the flexible high-speed I/O control module are classified by the following data types.
Data type
Control data
Monitor data
Do not write data to the system areas and areas whose data types are monitor in the buffer memory. Writing
data into these areas can cause the malfunction of the module.
