If, for example, 252 isspecified as the beginning word for writing,and two words of data are specified,then 253 will become the last word for writing data, and the command will not beexecuted because SR 253 is beyond the writable range.258SectionHost Link Commands4-54-5-9 LR AREA WRITE – WLWrites data to the LR area, starting from the specified word.
