Event Bit 63
In the Perception software the event bits are combined within one channel and
labeled as CH1_1 through CH1_64. The counter/timer channels are referred to
as CH2 through CH4.
Counter input The counter input is the actual signal input. The counter value
will be modified on each rising edge of this signal. The maximum input rate is
10 Mhz.
Direction The direction signal determines if the counter will be incremented
(direction = "0"), or decremented (direction = "1") on each rising edge of the
counter input.
Reset The reset signal will reset the counter to zero. The reset enabling as well
as the active level is determined under software control.
The actual mode of the counter/timer channel is selected in the Perception
software.
