Ink/Cursor Start Address Select Bits [7:0]
These bits define the start address for the Ink/Cursor buffer. The Ink/Cursor buffer must be posi-
tioned where it does not conflict with the image buffer and half-frame buffer – see Memory Map-
ping for details.
The start address for the Ink/Cursor buffer is programmed as shown in the following table where
Display Buffer Size represents the size in bytes of the attached DRAM device (see MD[7:6] in
Summary of Configuration Options):
The Ink/Cursor image is stored contiguously. The address offset from the starting word of line n to
the starting word of line n+1 is calculated as follows:
Ink Address Offset (words) = REG[04h] + 1
Cursor Address Offset (words) = 8
