5.4.1 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. Four built-in pulse generators work by the same
clock. In the SP-5000-CXP4, the clock is set at 86.4 MHz.

This is where you select one of the 4 pulse generators in order to set or modify its parameters.

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

as the minimum
active width.
