Q.9.4

Is the receive indication issued even when a Raw cell is received?

A.9.4
The receive indication is not issued when a Raw cell is received. When a Raw cell is received, it is stored in the
receive buffer as Raw cell data and is reported only by the Raw cell receive interrupt (bits RCR7 to RCR0 of the
GSR register).
On the transmission side, the transmit indication is issued even when a Raw cell is transmitted.
