BADSIZEI
UNSUPHFI
RST_DONEI
Reserved
CBAEXI
SDGMDI
SBIC1FPSI
The Bad Size interrupt status bit (BADSIZEI) indicates that the RAPI-12 block received a
segment of incorrect size. If such an interrupt occurs, the Any-PHY specification will be
violated. BADSIZEI remains valid when interrupts are disabled and may be polled. Under
normal operation, this interrupt will never occur. Assertion of this interrupt should trigger a
chip reset.
The IQM-12 interrupt status bit reports a datagram with an unsupported header format was
detected. (In particular, Frame Relay datagrams carrying a 16, 17, or 23 bit DLCI, or PPP
datagrams with PID(H) odd and/or PID(L) even). UNSUPHFI remains valid when interrupts
are disabled and may be polled.
The RST_DONEI status bit reports the ending of the hardware reset or software reset
operation, it indicates that all of the flip-flops and internal RAMs have been initialized. The
RST_DONEI cannot be enabled but can be polled to indicate reset completion.
The reserved bit can be set to any value.
The Chunk Buffer Allocation Exceeded Interrupt status bit reports chunk buffer allocation
exceeded events. CBAEXI remains valid when interrupts are disabled and may be polled.
The Small Datagram discard Interrupt status bit reports small datagram discard events due to
insufficient bandwidth to sustain the number of small datagrams (less than 40 bytes) received.
SDGMDI remains valid when interrupts are disabled and may be polled.
The SBIC1FPS Interrupt status bit reports C1FP realignment events on the SBI bus.
SBIC1FPSI remains valid when interrupts are disabled and may be polled.
