4.7.4.38
Code:
Definable area: 00h ≤ m ≤ 01h
Function:
Cursor position does not change.
Select RAM or FROM bit image by Select Bit image data memory 'm'.
Set Bit image defined Y size to the same Y size of the bit image defined in memory.
A portion of the Defined bit image can be displayed by setting Bit image scroll display Y size less
than Defined bit image Y size, or by changing Bit image data definition address.
Note for aE = 01h – 04h:
Bit image data can be read from 010000h to 04FFFFh continuously (bit image display can cross a
block boundary).
If the bit image memory area 010000 – 04FFFF is exceeded, undefined data is displayed.
Note: Scroll speed is approximate. Depending on the scrolling area, scroll may reduce in speed or
flicker. See also 4.7.4.39 Horizontal scroll display quality select and 3.1 Timing Unit.
