JPEG Interface Compression Control Register

Fields

DINSWAP

Byte/Halfword Swap

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]

DINLC

Count Mode Setting for Stopping Input Image Data Lines

0 (0): Count mode for stopping the input of image data lines is off

1 (1): Count mode for stopping the input of image data lines is on

DINRCMD

Input Image Data Lines Resume Command This bit is valid only when the count mode for stopping the input of image data lines is on. Setting this bit to 1 resumes reading input image data. This bit is always read as 0.

DINRINI

Address Initialization when Resuming Input of Image Data Lines This bit is only valid when the count mode for stopping the input 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 input of image data lines is restarted

1 (1): The transfer address is initialized when the input of image data lines is restarted

JOUTSWAP

Byte/Halfword/Word Swap Output coded data in compression 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 - Word - byte swap]
