No receive buffer full indication
Receive buffer block of the GHDLC is full. The blocks have been
switched.
No buffer overrun indication
Two consecutive full interrupts were received without a GHDLC
access to the status register in between, i.e. a buffer was missed.
No transmit buffer empty indication
The transmit buffer block currently being transmitted over the
GHDLC channel has been emptied
No buffer underrun indication
A buffer containing an incomplete message has been emptied
without a continuation of the message in the other buffer
