iC-NQC 3
No.
1
Function, Parameter/Code
Description and Application Notes
GRAY
For Gray-coded data output clock cycles must be fully completed. An earlier
termination results in invalid data for the following read out cycle.
2
Startup
An invalid CRC keeps only SLO permanently on high, the incremental output to
A, B and Z is not blocked.

No.
1
Function, Parameter/Code
Description and Application Notes
GRAY
Gray-coded data output can be terminated at any time.
2
Startup
An invalid CRC keeps SLO and A, B and Z permanently on high (until an internal
reset).
3
Period counting
Following power-on and after an internal reset the period counter is initialized
with a value of zero (as all former chip releases).
If an input angle of exactly 0° is applied and a movement towards 270° is
following, the period counter counts to the value -1 (former chip releases
maintain the value of zero).

As a general rule our developments, IPs, principle circuitry and range of Integrated Circuits are suitable and specifically designed for appropriate use in technical
applications, such as in devices, systems and any kind of technical equipment, in so far as they do not infringe existing patent rights. In principle the range of
use is limitless in a technical sense and refers to the products listed in the inventory of goods compiled for the 2008 and following export trade statistics issued
annually by the Bureau of Statistics in Wiesbaden, for example, or to any product in the product catalogue published for the 2007 and following exhibitions in
Hanover (Hannover-Messe).
We understand suitable application of our published designs to be state-of-the-art technology which can no longer be classed as inventive under the stipulations
of patent law. Our explicit application notes are to be treated only as mere examples of the many possible and extremely advantageous uses our products can
be put to.
