... Normally, the serial interface data is loaded to the CXD2452R at the timing shown in 2) above. However, one exception to this is when the data such as SSGSEL and STB is loaded to the CXD2452R and controlled at the rising edge of SEN. For STB, see control data D62 to D63 STB in “Description of Operation”. ...

... Of the data provided to the CXD2452R by the serial interface, the CXD2452R loads D16 and subsequent data to the control register side when D08 is 0, and to the adjustment register side when D08 is 1. However, this assumes that the CXD2452R is selected by CHIP and that either the EBCKSM pin is low and D64 to D71 CHKSUM is satisfied or the EBCKSM pin is high. ...

... D26 to D35 Shutter speed data (number of horizontal intervals) specification The CXD2452R does not distinguish between the high-speed shutter and low-speed shutter modes. The interval during which Shut.FRM and Shut.HD are specified together is the shutter speed. At this time, Shut.FRM controls the XSG1, XSG2 output, and Shut.HD controls the XSUB output. Concretely, when specifying high-speed shutter, Shut ...

... See the timing charts for the vertical/horizontal sync signals in accordance with each mode. Note that when switching from monitoring drive to recording drive mode, the pixels decimated thus far must be cleaned. Concretely, this operation is supported by generating XSUB, but the CXD2452R facilitates this control by using D48 EXPOSE. (See the figure.) FRI ...

... D60 to D61 DSG The CXD2452R can stop control to the CCD pulses and pulses for the sample-and-hold and analog/digital conversion ICs by setting the DSGAT pin low. Conversely, when the DSGAT pin is set high, the controlled pulses can be switched as follows using the serial interface data. ...
