Note that all external inputs (from the camera, TTL inputs, and GPIO controls)
are resynchronized. The outputs from the look-up table are synchronous.
The LUT is programmed using a simple language. This language allows you to
create logical equations that specify the conditions that set particular outputs. See
also:
GPIO Control Block Programming Language
Note: There is a delay of two clock cycles between the inputs of the LUT
and its outputs. A clock cycle has a period of 30 nanoseconds, so the delay is 60
nanoseconds.
The signals in the GPIO Control Block are defined in the tables below.
Inputs to QuickCam are labeled I
n
(where n is an integer from 0 to 7) and
outputs are labeled Q
n
(where n is an integer from 0 to 15).
