*1: Reading is always available regardless of the write conditions. The item of which write condition is set to
"Setting mode" is changeable on setting mode only. Note that changing items during the operation
mode causes a write data error. In addition, it is necessary to turn on the setting change command
(YnB) for changing the setting.
