identifiers. The mapping of standard identifiers into the IDR registers is shown in
All bits of the receive and transmit buffers are ‘x’ out of reset because of RAM-based implementation
All reserved or unused bits of the receive and transmit buffers always read ‘x’.
1. Exception: The transmit buffer priority registers are 0 out of reset.
