mapped to 3 lines to 33 lines
respectively. Value 00000b disables the
N-line inversion, which is the POR
value. To avoid a fix polarity at some
lines, it should be noted that the total
number of mux (including the icon line)
should NOT be a multiple of the lines of
inversion (n).
Sets the LCD bias from 1/4 ~ 1/10
according to B2B1B0:
000: 1/4 bias
001: 1/5 bias
010: 1/6 bias
011: 1/7bias
100: 1/8 bias
101: 1/9 bias (POR for SSD1850)
110: 1/9 bias (SSD1850); 1/10 bias
