5.5.1 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. Four built-in pulse generators work by the same
clock. In the SP-5000-GE2, the pixel clock is set at 48 MHz.
5.5.2 Pulse Generator Selector
This is where you select one of the 4 pulse generators in order to set or modify its
parameters.

Set the counter up value (number of clocks, refer to Table 14) for the selected pulse generator.
If Repeat Count value is “0”, and if Pulse Generator Clear signal is not input, the pulse
generator generates the pulse repeatedly until reaching this counter up value.
