generates a maskable interrupt, and starts to receive data into the next buffer after one of
the following events:
E—Empty
Bits 14, 8, 6, 5—Reserved
W—Wrap (Final BD in Table)
I—Interrupt
L—Last in Frame
7-212
1. Receiving a user-defined control character
2. Detecting an error
3. Detecting a full receive buffer
4. Issuing the ENTER HUNT MODE command
5. Issuing the CLOSE Rx BD command
