755555....1111....2222 Register lengthUsually length is 1 word, you can set register length in “Add Tag” windows.Half wordContain 8bits (1byte). The value up to 255 can be stored. One register tag includes 2 tags (There is 1 tag inhigh-order, and 1 tag in low-order).Single wordContain 16bits (2 byte). The value up to 65,535 can be stored (in unsigned integer).This is the most basic register tag.Double wordContain 32bits (4byte). The value up to 4,294,967,295 can be stored (in unsigned integer). 1 double wordregister tag is stored by dividing into 2 consecutive tag numbers (high-order 16bits : tag number+1,low-order 16bits : tag number), and you can edit each tag independently. Only double word instruction andoperation with carry can handle the data of these tags as double word.
