Byte Notes Address

You can freely link bytes 1-2 and 3-4 with variables of the corresponding data type, as a 16-bit data word

It is possible, using different variables, to write simultaneously to bytes 1-2 or bytes 3-4. Avoid this
situation, since the data in bytes 1-2 or bytes 3-4 are then not unambiguous.
%QB33.2 and %QB33.3

It is possible, using different variables, to write simultaneously to bytes 5-6 or bytes 7-8. Avoid this

Example: If you write to bytes 3-4, using the variables CAN3_nOutW2_a and CAN3_dnOutD1_p then bytes 3-4 will be rewritten every time a
variable is processed. The data in bytes 3-4 are thus not unambiguous.
