Character’s Height Control
Bit 6-0: CRH6-CRH0 - These bits determine the displayed character height. Character, original 12 by 18 font
matrix, can be expanded from 18 to 71 lines. Refer to the table below. All of these bits will be
cleared to ‘0’ after power on.
If the setting value of CH0 – CH6 is great than 17, the algorithm will repeat at most 17 lines.
