Pulse Generator Pulse construction
5.4.3 Pulse Generator Length
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.
5.4.4 Pulse Generator Start Point
Set the active output start count value for the selected pulse generator.
However, please note that a maximum 1 clock jitter for the clock which is divided in the clock
pre-scaler can occur.
5.4.5 Pulse Generator End Point
Set the active output ending count value for the selected pulse generator.
5.4.6 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.
5.4.7 Pulse Generator Clear Activation
Set the clear conditions of clear count pulse for the selected pulse generator.
5.4.8 Pulse Generator Clear Sync Mode
Set the count clear method for the selected pulse generator.
In the case of Async Mode, if the clear signal is input during the length setting value, the
counter will stop counting according to the clear signal input.
In the case of Sync Mode, if the clear signal is input during the length setting value, the
counter will continue to count until the end of the length setting value and then clear the count.
Both modes clear the repeat count when the counter is cleared.
