JPEG encoded data contains the standardized marker codes such as SOI and EOI.
HBLK is set to high when JPEG data are output. The data length of one packet is multiple of MCU.
It is using 8 lines buffer memories (FIFO) when JPEG encoding. It is limited for the writing not to surpass the
reading because the writing speed is earlier than the reading speed. It is not limitation for low level period of
HBLK.
Also, following register setting, it is available to output by 4 bytes unit (multiple). HBLK is for data enable and
high level period continues clock of 4 multiples. It is not limitation for low level period of HBLK.
Also, when the JPEG data of 1V period is not 4 multiples, the data of address A5h makes to add after address
FFh and address D9h because it needs to become 4 multiples.
* Setting of reading 4 bytes unit
Address E6h D[3] J4BYTESW
“High” setting: JPEG output by 4 bytes unit
