The second command specifies the row address pointer
(0-127) 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 ROW0~127. This command
has no effect on ICONS. COM0 is mapped to ROW0 after
reset.
The second command specifies the number of lines,
excluding ICONS, to be displayed. With Icon is disabled
(POR), duties 1/16~1/128 could be selected. With Icon
enabled, the available duty ratios are 1/ 17~ 1/129.
