9.8 Set Multiplex Ratio

This command switches default 64 multiplex mode to any multiplex from 16 to 64, if Icon is

disabled (POR). When Icon is set enable, the corresponding multiplex ratio setting will be mapped

to 17 to 65. The chip pads ROW0-ROW63 will be switched to corresponding COM signal output as

specified in Table 2.

9.9 Set N-line Inversion

Number of line inversion is set by this command for reducing crosstalk noise. 3 to 33-line inversion

operations could be selected. At POR, this operation is disabled.

It should be noted that the total number of mux (including the icon line) should NOT be a multiple

of the inversion number (n). Or else, some lines will not change their polarity during frame change.

9.10 Set LCD Bias

This command selects a suitable bias ratio (1/4 to 1/9) required for driving the particular LCD panel

in use. The POR is set to 1/9 bias.

9.11 Set DC-DC Converter Factor

Internal DC-DC converter factor is set by this command. For SSD0858, 2X to 5X multiplying factors

could be selected. 2X to 5X factors are selected using this command.

9.12 Set Contrast Control Register

This command adjusts the contrast of the LCD panel by changing Vout of the LCD drive voltage

provided by the On-Chip power circuits. VOUT is set with 64 steps (6-bit) contrast control register. It

is a compound commands:
