Set N-line Inversion Register
Sets the inverted line number within range of 3 to 33 to improve the display quality by controlling the phase of the
internal LCD AC signal (M) by using the 2-byte instruction.
The DC-bias problem could be occurred if K is even number. So, we recommend customers to set K to be odd
number. K : D/N
D : The number of display duty ratio (D is selectable by customers)
N : N for N-line inversion (N is selectable by customers).
