AFAIK the receive acceptance filters always have to be used. However, 
those are very flexible and instead of selecting specific, single 
messages to receive you can also specify ranges - so the range you 
are probably looking for is something like 0x000 to 0x7FF to receive 
all standard CAN messages. 

The example you mentioned places ZERO entries into the "Standard 
Group" section of the table and several entries into the "Standard 
Individual Section".

You would need to make one entry in the "Standard Group" section 
specifying the lower and the upper bound of what you want to receive. 
The entry format is described in Figure 36 "Entry in Standard 
Identifier Range Table" in the User Manual.
