(1) reset all the registers and counters. reset is set to "l" (asynchronous to clk). reset state is in the standby state. (2) set the contents of the registers. there are 16 sets of registers, consisting of 4 bits each. the input data is composed of 8 bits. the leading 4 bits are for address and the following 4 bits are for data. the input data is latched at the rising edge of sclk. when load goes "h", the contents of the register become fixed at the rising edge of clk. (3) start image capture. after the contents of all the registers are fixed, start is asserted in synchronous with the rising edge of clk. then the control counters are reset to the initial value specified by the registers, and the image capture sequence starts. after the accumulation time defined by the registers 4 ~ 7, the analog image signals are outputted serially. the strb pulse is outputted in synchronous with the above. the number of active data on one frame is 1024 for the 2d image, 64 for the projection image, and 1 for the pixel average data; the number of data outputted in each modes is fixed by the combination of the above. when this chip finishes outputting the defined number of data, in the snapshot modes (md3=1), it automatically falls into the standby state. in the continuous modes (md3=0), once the image capture sequence starts, this chip carries on outputting the image data, unless start is asserted again or stop bit is set to "h" to force the chip into the standby state. the contents of the registers can be changed in the standby state. when start is asserted in the standby state or in the continuous image capture sequence, the control counters are, again, reset to the initial value specified by the registers, and the image capture sequence starts. if the register contents are changed before asserting start, M64285K outputs the data in a different mode. in the continuous output modes, register no. 2 including the stop bit is the only register that is allowed to be set. standby ?register setting ?reset state assert start (md3=0) image output over set stop=1 assert start assert start (md3=1) continuous mode image capture & output snapshot mode image capture & output

M64285K can output the inverted strb signal. if needed, set stinv to "1", else, set it to "0". M64285K outputs the optical black level before outputting the image data. bstrb selects whether to output the strb pulse at the optical black level output timing. if needed to be on, set bstrb to "1", else, set it to "0". powsv selects the power save state, in which power consumption is suppressed by reducing the amp current to be 1/10 while the chip is not outputting the analog data (ex.: just after reset, or in the accumulation period). the default state for powsv is 1 (on). besides, if the stdby bit is 1, power consumption is further suppressed by completely cutting the amp current while the chip is in the standby or halt state.
