When operating in 6 bits mode length mode, Y (Page) −address counter becomes 22 counter.
In Up−mode and Page = 21, after data has been written to or read, Y (Page) −address becomes Page = 0.
In Down−mode and Page = 0, after data has been written to or read, Y (Page) −address becomes Page = 21.
● Data read
When reading data, there are some occasions that dummy data read is needed. That is because when the
data read command is written into, the data corresponding to address counter is moved to the Output
Resister, and the contents of the output resister is transferred by the next data read command
Therefore when reading data next to power−on or next to address set (command SYE or SXE), dummy data
read is needed. See Fig. 13.
