13. Operational Timing 13.1. Chip Reset · Register Set · Image Capture Start The registers are set after resetting the chip. The timing chart below shows the operation up to the image capture. RESET is done asynchronous with CLK. The input data, SIN, which is used to set registers is inputted serially asynchronous with CLK and latched to the registers by the LOAD signal. Detailed timing of SIN and LOAD is given in "13.2. Register Set". After the contents of all registers have been decided, START is inputted in synchronous with the rise of CLK. Then, the counter used for controlling purposes is reset to the initial value which is specified by the register. Now, the image capture starts. If the period of LOAD or START is longer than 2 CLKs, the valid timing is the first CLK rise for LOAD, and the last CLK rise for START.

13.2. Register Set The input data SIN is composed of 8 bits (x16). The leading 4 bits are the address and the following 4 bits are data. The input data is transferred to a temporary register at the rising edge of SCLK (asynchronous with CLK), and when LOAD goes "H", the contents of the register become fixed at the rising edge of CLK.
