5.2 Timer
When the timer trigger source is set to off (see Section 5.2.5), a software timer
reset command starts the timer immediately (see Section 5.2.4).
The current timer value can be read via software. A start value can also be set, which means,
that the timer starts from this configured value instead from zero.
5.2.2
Timer Status
The timer has different states, which depends on the configuration and usage. The current
state can be read out by the register TimerStatus. The following list shows the available states:
Timer Idle
Timer is idle, and trigger source selection is set to off.
Timer Trigger Wait
Timer is waiting for a timer trigger signal.
Timer Delay
Timer is in timer delay count period.
Timer Active
Time is active and counts for the specified timer duration.
Timer Completed
Timer completed indicates, that the timer reached the timer duration count.
The timer remains in this state, until a new timer trigger event has been received, or the
timer is reset by a software command (see Section 5.2.4)
5.2.3
Timer Active, -Start and -End Signal
Timer Active
An asserted timer active signal indicates, that the timer has started counting the
configured duration period. The timer active signal is internally routed to the I/O control
block and can there be selected for output on the physical output line or on one of the
available leds.
Timer Start
The timer start is an event, which is generated, when the timer starts with the
timer duration period.
Timer End
The timer end is an event, which is generated, when the timer arrives its configured
timer duration value.
The timer start and end event signals can be used to trigger other blocks, like counter, timer,
acquisition, frame or exposure control.
5.2.4
Timer Reset
The timer can be reset by a software command. It performs a software reset of the timer
counter and starts the timer immediately (change to state timer active), when trigger source is
set to off; otherwise it goes into the state timer trigger wait.
5.2.5
Timer Trigger Source
The timer trigger source selects the events that will be the used to reset and to start the timer.
The following list of signals are available:
Off
Disables the timer trigger
Acquisition Trigger
Starts with the reception of the acquisition trigger event.
Acquisition Start
Starts with the reception of the acquisition start event.
