ICON Control Register ON/OFF
This instruction makes ICON enable or disable. By default, ICON display is disabled (ICON= 0). When ICON control
register is set to “1”, ICON display is enabled and page address is set to “16”. Then user can write data for icons. It is
impossible to set the page address to “16” by Set Page Address instruction. Therefore, when writing data for icons, ICON
control register ON instruction would be used to set the page address to “16”. When ICON control register is set to “0”,
ICON display is disabled.
