(3) Page Address Set
This command specifies the page address that corresponds to the low address when accessing the display data RAM
shown in Figure 4 from the MPU side. The display data RAM can access desired bits when the page address and column
address are specified. Even when the page address is changed, the display state will not be changed. For details, see the
Page address circuit of “Function Description”.
(4) Column Address Set
This command specifies the column address of the display data RAM shown in Figure 4. The column address is split
into two sections (higher 4-bits and lower 4-bits) when it is set (set continuously in principle). Each time the display
data RAM is accessed, the column address automatically increments (+), making it possible for the MPU to
continuously read and write the display data. The column address increment is stopped at FFH, and the FFH is specified
continuously. This must be noted when you want to access continuously. In this case, the page address is not changed
continuously. For details, see “Column Address Circuit” in Function Description.
