 Triggered on rising edge: Indicates if a triggered pulse generator is triggered on the rising edge of an

input

 Triggered on high level: Indicates is a triggered pulse generator is triggered on the high level of an

input

 Triggered on falling edge: Indicates if a triggered pulse generator is triggered on the falling edge of

an input

 Triggered on rising AND falling edges: Indicates if a triggered pulse generator is triggered on the

rising edge of an input and on the falling edge of an input

 Triggered on low level: Indicates if a triggered pulse generator is triggered on the low level of an

input

Pulse Period (ns)

Displays the value of the parameter, in nanoseconds, of a complete delay-width cycle of the pulse

generator. This value is computed every time the delay, width or granularity is modified and is available

regardless of the periodic mode.

Pulse Frequency (Hz)

Displays the frequency of the pulse generator. This value is computed every time the delay, width or

granularity is modified and is available regardless of the periodic mode.

The

software can generate two internal signals using the internal pulse generators. The behavior of each of

these two pulse generators is defined by a delay and a width . As shown in the accompanying diagrams,

the delay is the time between the trigger and the pulse transitions. The width is the time the pulse stays at

the active level before transitioning. The periodic mode, the delay determines the low time of the pulse.

Each pulse generator generates a signal that can be used as an input to the GPIO Control Block. A

triggered pulse generator needs an input signal that comes from an output of the GPIO Control Block.

Note: There is one clock cycle between the output signal of a pulse generator and the outputs of the GPIO

Control Block.

The labels for the inputs from the pulse generators in the GPIO Control Block programming languages

are:

 I7, for pulse generator 0
