Code:
Definable area: 00h ≤ m ≤ 02h
Function:
Cursor position does not change.
Select RAM, FROM or Display Memory 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 display Y size less than
Defined bit image Y size, or by changing Bit image display X size and/or Bit image data definition
address.
If the bit image extends beyond the currently-selected window, only the portion within the current
window is displayed.
When the bit image is being written to the Display Memory, if the bit image memory area is
exceeded, undefined data is displayed.
Note for aE = 01h – 04h:
Bit image data can be read from 010000h to 04FFFFh continuously (bit image display can cross a
block boundary).
