RBC7-0 ... Receive Byte Count
Eight least significant bits of the total number of bytes in a received message. Bits
RBC4-0 indicate the length of a data block currently available in the RFIFOD, the other
bits (together with RBCHD) indicate the number of whole 32-byte blocks received.
If exactly 32 bytes are received RBCLD holds the value 20
