LC8213K
CPU interface
The LC8213K has an 8-bit data bus. Various aspects of the operating mode can be set by accessing the interface
registers. Since the LC8213K provides interface pins for a DMA controller, DMA transfers with memory on the CPU
bus are supported.
Image memory interface
The image memory has a 16-MB address space. A data bus width of either 8 or 16 bits can be selected.
DMA transfer function
This function performs DMA transfers between image memory and I/O devices using the on-chip DMA controller. The
number of lines of data transferred can be set to any value up to 64k lines.
Data transfers
Data can be transferred between the CPU bus and the image memory bus without encoding or decoding.
Pad bit processing
Applications can select whether or not to perform pad bit processing. Pad bit processing consists of adding bits set to 0 at
the end of each line of encoded data so that the data for that line is an even multiple of 8 bits.
Parameter settings
The LC8213K supports the following parameters, which can be set to any value in the indicated range.
Number of bits processed on a single line (in byte units): 1 to 8k bytes
Source document width (in byte units):
1 to 8k bytes
Number of lines processed:
1 to 64k lines
Minimum number of bits transmitted per line:
0 to 64k bits
K parameter for MR encoding:
0 to 64k
Number of lines handled in DMA transfers:
1 to 64k lines
Number of EOL codes that form the RTC code:
0 to 255
Since the source document width and the number of bits processed on a single line can be set separately, the LC8213K
supports encoding or decoding the data for a subsection of the source document.
