*1. This area is not latched (backed up). It can be changed to the latched (backed-up) area by parameter
setting.

setting.
*2. This area is latched (backed up). It can be changed to the non-latched (non-backed-up) area by

*3. The characteristics of latch (backup) cannot be changed using parameters.
Counter numbers not used as counters can be used as data registers to store numeric values.
