Via SECLK(1:0) in control word 3B the clocked filtering
for the I/O signals and overcurrent messaging can also
be deactivated. The same behavior can be obtained by
setting BYP0, BYP1, BYP2 and BYP3 in control word
1 (addresses 0x14 and 0x15) together with BYPSCF
in control word 4 (address 0x1A); all filters are avoided
by way of a bypass circuit. Here it must be noted that
interferences in the line can lead to the unwanted dis-
play of interrupts.
Forced shutdown of output stages
The output stages can be forcibly shutdown at input
POE. A ’1’ enables logic access to the drivers; a
’0’ disables this. This function allows a processor-
independent watchdog to lock the outputs in the event
of error, for example. An integrated pull-down resistor
increases safety.
DESIGN REVIEW: Notes On Chip Functions
iC-JX X2 (and previous)
No. Function, Parameter/Code
1 Leakage current beyond operating conditions (Elec-
trical Characteristics Item No. 019
Description and Application Hints
During operation, supply voltages VCC, VDD and
VB1..VB4 must already be present and stable
to avoid elevated leakage currents at pins IOx
(x=1..16).

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.
