... Normally, the serial interface data is loaded to the CXD2450R 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 CXD2450R and controlled at the rising edge of SEN. For STB, see control data D62 to D63 STB in "Description of Operation". ...

... 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 VSUB, but the CXD2450R facilitates this control by using D48 EXPOSE. (See the figure.) FRI ...

... D60 to D61 DSG The CXD2450R can apply 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. ...
