Pulse Generator Length
Set the counter up value (number of clocks, refer to Table 12) 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.
5.5.4
Pulse Generator Start Point
Set the active output start count value for the selected pulse generator.
However, please note that a maximum jitter of 1 clock can occur for the clock which is divided in the
clock pre-scaler.
5.5.5
Pulse Generator End Point
Set the active output ending count value for the selected pulse generator.
5.5.6
Pulse Generator Repeat Count
Set the repeating number of the pulse for the selected pulse generator. After Trigger Clear
signal is input, the pulse generator starts the count set in Repeat Count. Accordingly, an active
pulse which has a start point and end point can be output repeatedly.
However, if Repeat Count is set to "0", it works as a free-running counter.
