Fine horizontal offset. These 2 bits select a fine offset, ranging from 0 to 3 quarter
characters; see Table 71.
Text area start. These 6 bits select an offset of 0 to 63 full-width characters; see
Table 70.
Fringing colour. These 4 bits select the fringing colour. One of 16 colours can be
specified; see Table 58.
Fringing directions. The fringing direction is selected by setting one of these bits to a
logic 1. For example, when FRDN = 1, the fringing direction is North. See Table 57.
