Opecore CAN: Checking for Receiving Message

Hi all,

I have sucessfully checked the initialisationand transmit operations of 
my CAN opencore (Linux PC --- > Laptop+CAN Analyser) with the following 
code:

---------MemoryMap CAN = 0x3000  -----------------------

Now my concern is to send a CAN Msg from CAN Analyser and see this on my 
Linux PC. what should I do ?
The first thing I noticed is there is no Rcv Registers (Then I though 
maybe it uses the same Tx by receiving)
So
1) am I rigth by considering that: Rx registers = Tx registers ? which 
registers should I check for a Message send from the CAN Analyser ?
2) In which sequencies should I set those registers in order to activate 
the receiving operation ?

within the CAN_REGISTERS Files there is no mentions about Receive 
registers

transmit_buffer_status;

((~extended_mode) & (addr == 8'd18) | extended_mode & (addr == 8'd24)) & 
transmit_buffer_status;

((~extended_mode) & (addr == 8'd19) | extended_mode & (addr == 8'd25)) & 
transmit_buffer_status;

So I would appreciate any advice allowing me to move forward.
