Trigger
The board accepts trigger input signals which allow, for example, image acquisition
to be synchronized with external events. Each PSG has 4 trigger controllers.
Multiple auxiliary signals can trigger a trigger controller; however, you can
program only one per trigger controller as a trigger input signal
When received in TTL format directly, the signal must have a maximum
amplitude of 5 V. A signal over 2 V is considered high, while anything less than
0.8 V is considered low; the transition of 0.8 V to 2 V is considered to be the rising
edge.
If using the trigger to start acquisition, the trigger signal’s pulse width must be
greater than two pixels; if using the trigger to start the timer, the trigger signal’s
pulse width must be greater than two clock periods of the timer. To determine the
timer period, take the inverse of the pixel or timer’s clock frequency, respectively.
For example, if the pixel frequency is 12.27 MHz, the minimum pulse width is 2
x 1/12.27 MHz (approximately 163 nsec).
