5 Counter & Timer
FrameTrigger Resets with the reception of the frame trigger.
Frame Start Resets with the reception of the frame start event.
Frame End Resets with the reception of the frame end event.
Frame Burst Start
Resets with the reception of the frame burst start event.
Frame Burst End Resets with the reception of the frame burst end event.
Exposure Start Resets with the reception of the exposure start event.
Exposure End Resets with the reception of the exposure end event.
User Output 0 ... 7 Resets the counter as long as the selected user output bit is asserted. The
counter remains in reset state until the selected user output bit is deasserted again (see
Section 4.7).
Counter 0 ... 3 Start
Resets with the reception of the chosen counter start event.
Counter 0 ... 3 End Resets with the reception of the chosen counter end event.
Timer 0 ... 3 Start Resets with the reception of the chosen timer start event.
Timer 0 ... 3 End Resets with the reception of the chosen timer end event.
Action 0 ... 3 Resets with the reception of the chosen action signal event.
Software Signal Pulse 0 ... 7
Resets with the reception of chosen software signal pulse event
(see Section 4.7).
Line Input Resets when the specified counter trigger activation condition is met on the chosen
line.
Line input source has additionally a activation configuration, which needs to be set
accordingly. Following configuration values are available:
Rising Edge Resets with the rising edge on the selected line input.
Falling Edge
Resets with the falling edge on the selected line input.
Both Edges
Resets with any edge on the selected line input.
Activation configuration has only effect when line input is selected as a counter
reset source, otherwise this configuration is ignored.
5.2 Timer
Four general purpose timers are available in the camera (Timer0 ... Timer3). A timer can be
used to generate a timed pulse - for instances a strobe signal - or to generate an event after a
predetermined duration. Each timer can be configured individually by software and controlled
by timer trigger events. This section describes the configuration and the function of the timers.
Fig. 5.2 shows the structure of one timer. It contains a timer trigger source and activation
block. Furthermore it has three output signals: A timer active status signal, which is routed to
the I/O control block (see Chapter 6) and timer start and end event signals, which can be used
to trigger other blocks, like counter, timer, acquisition, frame or exposure control (see Section
5.2.3).
