Description
The second command specifies the number of lines,
excluding ICONS, to be displayed. With Icon is disabled
(POR), 16~64 mux could be selected. With Icon
enabled, the available mux are 17~ 65.

The second command sets the n-line inversion register
from 3 to 33 lines to reduce display crosstalk. Register
values from 00001b to 11111b are 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).
