Table 4
Input write I²C Bus parameter
In case of non-standard signals the field order is indeterminate (e.g. AAA... , BBB... ,
AAABAAAB..., etc.). Therefore a special filtering algorithm is implemented, which can be
switched on by the I²C Bus parameter VCRMODEM/VCRMODES. It is recommended to
set the I²C Bus parameter VCRMODEM=1. In other case (VCRMODEM=0) an additional
