SEGRAM has segment control data and segment pattern data. During 1-line display mode, COM0 (COM17)
makes the data of SEGRAM enable to display icons. When used in 2/4-line display mode COM0 (COM33) does
that. Its higher 2-bit are blinking control data, and lower 6-bits are pattern data (refer to Table 5 and Figure 8).
