2.2.4 Display Data Area Partition, Display/Hide
OKI Semiconductor
The effective data area of the display output can be divided into four partitions. Horizontal division or vertical
division can be selected, and the data buffer address of data to be displayed in each of the four areas can be
specified individually.
Also, the specified area can be hidden. Hidden areas are not used to read the data buffers.
