Im using the LPC1778 uC and the user manual claims this point : "The Receive Interrupt Bit is not cleared upon a read access to the Interrupt Register. Giving the Command “Release Receive Buffer” will clear RI temporarily.
If there is another message available within the Receive Buffer after the release
command, RI is set again. Otherwise RI remains cleared."
This statement is hinting the fact that there may be 2 receive buffers for when data is received over CAN.

Any idea as to whats the size of the receive buffer in CAN? Is it only 8 bytes before a data overrun occurs?
