| DOUTSWAP | Byte/Word Swap Output image data in decompression is swapped. 0 (000): (1) (2) (3) (4) (5) (6) (7) (8) 1 (001): (2) (1) (4) (3) (6) (5) (8) (7) [Byte swap] 2 (010): (3) (4) (1) (2) (7) (8) (5) (6) [Halfword swap] 3 (011): (4) (3) (2) (1) (8) (7) (6) (5) [Halfword - byte swap] 4 (100): (5) (6) (7) (8) (1) (2) (3) (4) [Word swap] 5 (101): (6) (5) (8) (7) (2) (1) (4) (3) [Word - byte swap] 6 (110): (7) (8) (5) (6) (3) (4) (1) (2) [Word - Halfword swap] 7 (111): (8) (7) (6) (5) (4) (3) (2) (1) [Word - Halfword - byte swap] |
| DOUTLC | Count Mode for Stopping Output Image Data Lines 0 (0): Count mode for stopping the output of image data lines is off. 1 (1): Count mode for stopping the output of image data lines is on |
| DOUTRCMD | Output Image Data Lines Resume Command This bit is valid only when the count mode for stopping the output of image data lines is on. Setting this bit to 1 resumes writing image data. This bit is always read as 0. |
| DOUTRINI | Address Initialization when Resuming Output of Image Data Lines This bit is only valid when the count mode for stopping the output of image data lines is on. Set this bit before writing 1 to the data-line resume command bit. 0 (0): The transfer address is not initialized when the output of lines of image data is restarted. 1 (1): The transfer address is initialized when the output of lines of image data is restarted |
| JINSWAP | Byte/Word/Longword Swap Input coded data in decompression is swapped. 0 (000): (1) (2) (3) (4) (5) (6) (7) (8) 1 (001): (2) (1) (4) (3) (6) (5) (8) (7) [Byte swap] 2 (010): (3) (4) (1) (2) (7) (8) (5) (6) [Halfword swap] 3 (011): (4) (3) (2) (1) (8) (7) (6) (5) [Halfword - byte swap] 4 (100): (5) (6) (7) (8) (1) (2) (3) (4) [Word swap] 5 (101): (6) (5) (8) (7) (2) (1) (4) (3) [Word - byte swap] 6 (110): (7) (8) (5) (6) (3) (4) (1) (2) [Word -Halfword swap] 7 (111): (8) (7) (6) (5) (4) (3) (2) (1) [Word - Halfword - byte swap] |
| JINC | Count Mode Setting for Stopping Input Coded Data 0 (0): Count mode for stopping the input of coded data is off. 1 (1): Count mode for stopping the input of coded data is on |
| JINRCMD | Input Coded Data Resume CommandThis bit is valid only when the count mode for stopping the input of coded data is on. Setting this bit to 1 resumes reading input coded data. This bit is always read as 0. |
| JINRINI | Address Initialization when Input Coded Data is Resumed This bit is only valid when the count mode for stopping the input of coded data is on. Set this bit before writing 1 to the data resume command bit. 0 (0): The transfer address is not initialized when the input of coded data is restarted. 1 (1): The transfer address is initialized when the input of coded data is restarted. |
| OPF | Specifies output image data pixel format. 0 (others): Setting prohibited 1 (01): ARGB8888 2 (10): RGB565 |
| HINTER | Horizontal Subsampling Subsamples horizontal output image data. 0 (00): No subsampling 1 (01): Subsamples output data into 1/2. 2 (10): Subsamples output data into 1/4. 3 (11): Subsamples output data into 1/8. |
| VINTER | Vertical SubsamplingSubsamples vertical output image data. 0 (00): No subsampling 1 (01): Subsamples output data into 1/2. 2 (10): Subsamples output data into 1/4. 3 (11): Subsamples output data into 1/8. |
