(3) Page Address Set
This command specifies the page address that corresponds to the low address when accessing the display data RAM
shown in Fig. 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 Fig. 4. The column address is set
(basically successively) by dividing it into high-order four bits and low-order four bits. Since the column address is
automatically incremented by 1 whenever the display data RAM is accessed. The MPU can successively read/write the
display data. The column address stops the increment at C7H. In this case, the page address is not changed successively.
For details, see the Column address circuit of “Function Description”.
