8 bits CPU address bus for selection of parameter setting internal register.
8 bits CPU data bus for parameter data’s I/O.
Chip select input of CPU bus. (negative)
Write enable input to parameter setting internal register. (negative)
Read enable input to parameter setting internal register. (negative)
If it is "L", interrupt request to CPU. (negative)
Clock input.
If it is "L", hardware reset will be executed. Internal circuit will be initialized and internal register will be set
by default value.
In the period of hardware reset, all I/O pins will be changed to input mode.
If it is "H", change to the power down mode.
Horizontal synchronous signal input. (positive)
Vertical synchronous signal input. (positive)
If it is "H", pixel I/F is input mode and compression data I/F is output mode.
If it is "L", pixel I/F is output mode and compression data I/F is input mode.
