Error Protocol
Out of the errors enabled by EMASKE both the first
error (under ERR1) and last error (under ERR2) which
occur after the iC-MSB is powered up are stored in the
EEPROM.
The EEPROM also has a memory area in which all oc-
curring errors can be stored (ERR3). Only the fact that
an error has occurred can be recorded, with no infor-
mation as to the time and count of appearance of that
error given. Error recording can be used to statistically
evaluate the causes of system failure, for example.

REVERSE POLARITY PROTECTION
The line drivers in iC-MSB are protected against re-
verse polarity and short-circuiting. A defective device
cable or one wrongly connected cause damage neither
to iC-MSB nor to the components protected against
reverse polarity by VDDS and GNDS.
The following pins are also reverse polarity protected:
PC, NC, PS, NS, PZ, NZ, ERR, VDD, GND and ACO
(as long as GNDS is only loaded versus VDDS). The
maximum voltage difference between the pins should
not exceed 6 V (respectively 8 V for pin ERR).
Note: If iC-MSB detects reverse polarity on power up,
the line drivers will not be enabled.
If the state of reverse polarity is resolved, iC-MSB re-
boots from the EEPROM and enables the line drivers.
