Bits
This crucial information defines the length of the cell and - based on the previous cells
- also the cell end position and the next cell start position within a frame.
If, for a given bit count, the Condition
value is longer
, it is truncated. If the condition
value is shorter, it is padded with 0. Both truncation and padding occur at the left side
of the condition value.
Examples:
●
if "Condition" is "=111000" and the "Bit order" is "MSB", then
– if "Bits" is 4, the truncated condition is "=1000"
– if "Bits" is 8, the padded condition is "=00111000"
●
if "Condition" is "=111000" and the bit order is "LSB" (accordingly, the condition in
"MSB" format would be "=000111"), then
– if "Bit s" is 4, the truncated condition is "=1000" for LSB and "=0001" for MSB
– if "Bits" is 8, the padded condition is "=00111000" for LSB and "=00011100" for
MSB

Condition
This text field is used to apply various conditions and functionalities for a cell. Among
others, it can be used to identify mandatory values (such as CRC checksum or ID) that
help to identify a frame. The numeric format and bit order of the condition value has to
match up with what is defined in the fields "Format" and "Bit order".
The following conditions are implemented:
