Text area end. These 6 bits assist in defining the width of the text area. The actual text
area width is the difference between the horizontal offset and the value specified by
these 6 bits; see Table 73.
Soft scroll area height. These 4 bits determine the visible scroll area height. One of
16 rows may be specified; see Table 64.
Soft scroll area position. These 4 bits specify the top display row of the soft scroll
area. One of 16 rows may be specified; see Table 63.
