List of Registers
Address
Register Name
R/W
Description
0
System setting
R/W
LSI H/W reset
Coding/decoding/image data through mode selection
Context selection (internal context/external context)
Byte swap ON/OFF of coded/image data on host bus
Bit swap ON/OFF of coded/image data on host bus
Image data I/O I/F (parallel I/F, serial I/F)
Image data bus bit width selection (32 bits/16 bits)
1
Parameter setting
R/W
Template selection (2-line/3-line template)
Setting of AT pixel position (up to 127) (If 0 is set, AT becomes
non-existent (default position))
Latch input/through input selection in external context input mode
2
Command
W
Context table RAM initialization command
Coding (decoding, through) start/end command
Start/stop command for R/W of context table RAM
Selection of temporary stop and terminating end
2
Status
R
Processing status (in process/end of processing)
Coded data read/write ready (ready/busy)
Marker code detection (SDNORM, SDRST, ABORT, others)
Interrupt request status
SC counter overflow
Processing mode (stop temporary/terminating end)
3
Interrupt enable setting
R/W
Interrupt enable setting correspondence to each of bits positions
of status register
4, 5
Pixel count setting
R/W
Setting the number of pixels on one line (in multiples of 16 or 32,
up to 10240 pixels)
6, 7
Line count setting
R/W
Setting the number of lines to be coded/decoded (up to 65535
lines)
8, 9
Processed line count
R
Setting the number of coded/decoded lines (up to 65535 lines)
A, B
Data write buffer
W
Buffer for writing coded data/image data/context table RAM data
from MPU into LSI (DMA transferable) (RAM address is
automatically incremented each time data is written.)
A, B
Data read buffer
R
Buffer for reading coded data/image data/context table RAM data
from LSI into MPU (DMA transferable) (RAM address is
automatically incremented each time data is read).
C
Marker code setting
W
Setting a terminal marker code in coding (SDNORM/SDRST)
C
Marker code read
R
Reading a marker code in decoding (SDNORM, SDRST, ABORT,
others)
D
Scaling
R/W
Reduction in coding (1/2 reduction in horizontal and vertical
directions, horizontal OR processing)
Magnification during decoding (×2 lengthwise and width)
Select throwing away the leading 1-byte of the coded data read
when decoding
Selecting the typical prediction
Selection of prohibiting line memory initialization
Note:
When the 8-bit bus is used for the data read/write buffer, use address A only.
Incase of the 16-bit buffer, only the word access is possible.
(The byte access is not possible.)
