is read as 1. Operation cannot be guaranteed if the start signal is issued again during processing.

Contents of registers in
Table 12-1
will be changed in following cases.
1. After user writes the registers again.
2. After reset operation is done.
3. After decompression of arbitrary JPEG file. In this case, the registers have the value from header of input
JPEG file after header parsing process.
Except in the above cases, it is possible to process next picture by only performing the process start signal after
process of a picture is completed.
