- Pulse Generator 0
Note: When Pulse Generator Repeat Count is set to "0", the camera is operating in Free Running mode.
However, based on the above default setting, Length=1, Start Point=0 and End Point=1, Pulse Generator stops at
High output. Therefore, if Start Point=0 and End Point=1 are configured, Length should be "2" as the minimum
active width.
6.5.1 Clock Pre-scaler
Clock pre-scaler (Divide Value) can set the dividing value of the frequency divider (12-bit
length) and the pixel clock is used for this. A built-in pulse generator works by the same
clock. In the GO-5000-USB, the pixel clock is 48 MHz.
