Receive Cell Buffer access. A cell extracted or copied from the data
stream is transferred from the internal receive buffer to the
microprocessor by 27 read accesses of RXRCEL. The accesses need
not be consecutive; it is allowed to access other registers in between.
Received cell(s) are indicated with bit 9 of ISR0 set. After read-out of
the last cell ISR0(9) is reset by the AOP.
