Commands

45/62

8.4

Page address set

This command specifies the page address of the DDRAM.

Specifying the page address and column address enables to access a desired bit of the

DDRAM. After the last column address (5FH), page address is incremented by +1. After the

very last address (column = 5FH, page = 8H), page address return to 0H.

Table 22.

Page address set

8.5

Column address set

This command specifies the column address of the DDRAM. The column address is split

into two sections (the upper 3–bits and lower 4–bits) when it is set.

Each time the DDRAM is accessed, the column address automatically increments by +1,

imaging it possible for the MCU to continuously access to the display data. After the last

column address (5FH), column address returns to 00H.
