The second command specifies the row address
pointer (0-63) of the RAM data to be displayed in
COM0. This command has no effect on ICONS. The
pointer is set to 0 after reset.
The second command specifies the mapping of first
display line (COM0) to one of ROW0~63. This
command has no effect on ICONS. COM0 is mapped to
ROW0 after reset.
