Error Indicator - Read/Write
1 - Bus error has occurred
0 - No error.
Interrupt / End of Interrupt - Read/Write
Reading this bit returns the status of the Block Fill or Block
Copy function interrupt (active high):
‘1’ - Interrupt request. Indicates Block Fill or Block Copy
function has completed.
‘0’ - No interrupt request. Indicates Block Fill or Block
Copy function has not completed.
Writing ‘0’ to this bit will clear the interrupt request; writing
‘1’ to this bit will generate an interrupt request.
This bit may be used to cancel a ‘broken’ graphics function
that never completes. Masking the interrupt by writing
INTEN = ‘0’, and writing INTEOI = ‘1’ will halt the current
Graphics Accelerator function.
Background - Read/Write
When this bit is ‘0’ during remap (REMAP = ‘0’), source
image pixels that have a value of ‘0’ are unaffected
(transparent) when they are copied to the destination
image.
When this bit is ‘1’ during remap (REMAP = ‘1’), source
image pixels that have a value of ‘0’ are copied to the
destination image with the color value in the BG field of the
BACKGROUND
Reading this bit returns a valid value only when EN = '1'.
Pixel Expansion Mapping Function Enable - Read/Write
The value of REMAP enables or disables the Pixel
Expansion Mapping Function:
32 bits per pixel (24 bpp unpacked)
24 bits per pixel packed
16 bits per pixel
